DJI Agras T100 OEM LiDAR Module (International Version)

The DJI Agras T100 OEM LiDAR Module (International Version) is the laser ranging sensor at the front of the T100 airframe — the domed unit with its own signal cable that DJI's overseas parts lists call the T100 laser radar module. It is one of the three sensing systems the T100 flies on, alongside millimeter-wave radar and the Penta-Vision camera system, and it feeds the aircraft's terrain following, altitude holding, and obstacle sensing. This is the international (overseas) version of the module. The USA version is a separate Ares Acres listing, and the two are kept apart on purpose.

🔧 Component Overview

The T100 is a heavy aircraft working close to the ground, over crops, around trees, poles and wires, often in dust, spray drift, and low light. DJI equips it with three different kinds of sensing so that no single condition blinds it: millimeter-wave radar, the Penta-Vision camera system, and this LiDAR module.

LiDAR works by timing pulses of laser light that bounce back from whatever is in front of and below the aircraft. From those returns the aircraft builds a picture of distance — the ground under it, the canopy ahead, the pole at the end of the row. DJI's published T100 material says downward sensing assists terrain following and altitude stabilization, and the T100's AR display can show LiDAR point clouds for takeoff, landing, and night work.

The module itself is a compact finned housing with a domed optical window on its face and a signal cable leaving the back. The fins carry heat away from the electronics. The dome is the window the laser and its returns pass through — and the part of the assembly most exposed to the field.

Over a working season the LiDAR lives with:

• Spray droplets and chemical film settling on the dome
• Dust and chaff thrown up during takeoff and landing
• Grit-laden wiping with whatever cloth is to hand
• Branch strikes and canopy brushes at low altitude
• Transport vibration with the aircraft folded on a trailer
• Heat soak in summer sun on the staging pad
• Moisture and temperature swings between night and day work
• Hard landings that load the mount and the module together

Most of what goes wrong around the LiDAR happens to its outer surface or its mounting first. The module behind them is a sealed sensor. That is why the checks below start with what is not the module.

The finned housing is also why the module tolerates long summer days: heat leaves through the fins rather than building up behind the dome. Keep those fins free of caked residue and mud — a module buried in dried slurry runs hotter than it was designed to.

Replacement of the module is genuinely called for when the housing is cracked or impact-damaged, the module's own cable or connector is damaged, moisture has entered the unit, or the aircraft continues to report a LiDAR fault after the dome has been cleaned or replaced, the mount checked, and the connector reseated.

⚙️ Functional Purpose

The LiDAR's engineering role is distance measurement that does not depend on daylight or on contrast in the scene.

It contributes to:

• Terrain following — holding a set height above uneven ground and slopes
• Altitude stabilization close to the canopy
• Obstacle sensing ahead of the aircraft, alongside radar and vision
• Point-cloud display on the remote controller for takeoff, landing, and night operation

The three sensing systems cover each other's weak points. Cameras need light and texture. Radar sees through dust and spray but resolves fine shapes less well. LiDAR resolves shape in the dark. When one system is degraded, the aircraft leans harder on the others — which is also why a degraded LiDAR does not always announce itself loudly.

What the LiDAR does not do matters as much:

• It does not make wires safe. DJI states that linear obstacles such as wires must still be marked, and that the aircraft cannot automatically avoid moving objects
• It does not see through a dirty or scratched dome; it measures through it
• It does not compensate for a mount that has moved — it reports distance along whatever direction it is pointed
• It does not change the aircraft's region configuration; it must match it

DJI also notes that effective sensing range varies with ambient light, rain, fog, and the material, position, and shape of the obstacle. No sensor on the aircraft is a guarantee, and a page that implied otherwise would be wrong.

🔍 Diagnosis — the dome fails first and looks like the module

The LiDAR measures through its dome. Anything on or in that window — chemical film, dried droplets, fine scratches, a crack — scatters or blocks the laser before it leaves and again when it returns. To the aircraft, a fogged dome looks exactly like a weak sensor: shorter range, noisy returns, unstable terrain following, intermittent sensing warnings.

That is the misdiagnosis this part invites. Operators see a LiDAR warning, assume the module has failed, and replace the expensive half of an assembly whose cheap half was the problem.

Work outward-in, in this order:

• Clean the dome properly. Rinse off chemical residue first, then clean with a soft lens cloth. Dry wiping a dusty dome is how most scratches get there.
• Inspect the dome under a light. Turn it against a bright source and look for haze, crazing, and scratch arcs. A dome that stays cloudy after cleaning is damaged, and the dome is listed separately.
• Check the mount. Look for cracks, bent tabs, or a module that sits crooked. A module pointing in the wrong direction measures the wrong thing perfectly.
• Reseat the connector. Power down, disconnect, inspect both ends for residue or bent pins, reconnect firmly.
• Check the version. An international-version module in an aircraft configured for another region, or the reverse, is a mismatch to rule out before calling anything faulty.

Signs that point past the dome to the module itself:

• A cracked or deformed housing, or broken cooling fins
• Moisture or condensation visible inside the dome
• A damaged cable or connector on the module's own lead
• A LiDAR fault that persists with a clean, undamaged dome, a sound mount, and a reseated connector

Signs that are not the LiDAR at all:

• Vision-system warnings in good light — check the cameras
• Radar warnings in dust or rain — check the radar surfaces
• Unstable height hold on bare, highly reflective, or very soft ground — note the surface before blaming a sensor

Go through the cheap checks first, while that information is still cheap. If the dome is clean and sound, the mount is straight, the connector is good and the version matches, and the fault remains, the module is the part, and this is the right one to fit.

⚠️ Common Replacement Indicators

Replace the LiDAR module when inspection confirms one of these:

• LiDAR fault or sensing warning that persists after the dome, mount, and connector checks
• Cracked, dented, or impact-deformed module housing
• Broken cooling fins or a housing pushed out of shape by a strike
• Moisture, condensation, or residue inside the dome
• Damaged signal cable, crushed sheath, or exposed conductors
• Damaged connector housing or bent pins on the module lead
• Module damaged together with its mount in a crash or ground strike
• Terrain following that remains unstable with a clean, sound dome and a straight mount
• Point-cloud display missing or fragmented after other causes are ruled out
• A module removed from service after a version mismatch, with the correct version required

Inspect these first, because they produce the same symptoms and are often the real cause:

• The dome — residue, haze, scratches, or a crack
• The LiDAR mount — cracks, bent tabs, loose screws
• The connector at both ends
• Aircraft firmware and the module's version against the aircraft's configuration
• The other sensing systems, when warnings are general rather than LiDAR-specific

A LiDAR that has simply flown many hours is not a reason to replace it. There is no service interval for this module; it is replaced when it is damaged or demonstrably faulty.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the flight battery
• Photograph the LiDAR area — module orientation, cable routing, connector position
• Confirm the version of the module you are removing — international, not USA
• Inspect the mount for cracks or bent tabs while the module is still on it
• Clean the area around the module so grit does not fall into the connector
• Handle the new module by its housing, never by the dome or the cable

During installation

• Disconnect the signal cable by its connector body, not by the lead
• Remove the old module evenly from the mount and keep the screws together
• Seat the new module squarely on the mount so it points exactly as the old one did
• Tighten the screws evenly and firmly; DJI does not publish a torque figure for this joint, so do not over-tighten into the housing
• Route the cable along its original path, clear of the propeller arcs and any chafe point
• Connect firmly until the connector is fully seated
• Keep fingers and tools off the dome; fingerprints are contamination

After installation

• Rock the module by hand — it should not move on its mount
• Power up and confirm the aircraft recognizes the LiDAR with no sensing warning
• Check the point-cloud display on the remote controller before flight
• Hover at low height and confirm stable height hold over a known surface
• Run a short terrain-following pass over familiar ground before returning to field work
• Record the module version and date in the aircraft's maintenance log

Maintenance between jobs. Rinse the dome after every chemical day before residue dries, clean with a soft lens cloth only, and include the dome and mount in every pre-flight walk-around. A clean dome is the cheapest sensing upgrade on the aircraft.

🚜 Necessary For

This module is for operators and technicians keeping international-version T100 aircraft flying:

• DJI Agras T100 operators running international-version aircraft
• Commercial spray and spreading contractors working rolling or terraced ground
• Orchard and vineyard applicators flying close to canopy and trellis
• Operators who fly night or low-light work and depend on LiDAR returns
• Agras service centres and repair technicians
• Fleet managers holding sensing spares for multi-aircraft operations
• Operators rebuilding the front sensing area after a strike

This is not the part you need if:

• Your aircraft is a USA-configured T100 — order the USA-version module
• The dome is scratched or hazed and the module is otherwise sound — replace the dome
• The mount is cracked and the module is undamaged — replace the mount
• Your warnings come from the radar or the vision cameras rather than the LiDAR
• You need a full sensing assembly — this is the LiDAR module alone

---

💡 Why This Part Matters

The LiDAR is the sensor that keeps working when the light goes. On a T100 flying terraces, orchards, and night jobs, it carries much of the work of holding height and reading the ground ahead.

Its value is matched by how easily it is wrongly blamed. The module sits behind a window that collects everything the field throws at it, so the most common LiDAR complaint is really a dome complaint. Treat the dome, the mount, and the connector first, and many LiDAR faults end there.

There is also a time cost to guessing. A module swapped on suspicion, when the dome was the fault, leaves the operator with the same warning on the next flight and one fewer sensible explanation. Working outward-in — dome, mount, connector, version, module — turns a vague sensing complaint into a repair with a clear end.

When the module itself is damaged — a cracked housing, water inside, a ruined cable — nothing else restores the sensing it provides. The aircraft can still fly on its other systems, but terrain following and low-light confidence suffer, and the operator ends up flying higher, slower, or not at night.

Matching the version matters just as much. DJI builds this module in a USA version and an international version, and we keep them as separate listings rather than one listing with a guess in it. Match the version to the aircraft, and the replacement arrives as the right part the first time.

And when the module is not the problem, the checks above will have said so. A new dome or a new mount is the honest repair far more often than a new sensor.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 LiDAR module? It is the laser ranging sensor at the front of the T100. It measures distance to the ground and to obstacles and supports terrain following, altitude stabilization, and obstacle sensing alongside the radar and vision systems.

Which version is this? The international (overseas) version. The USA version is a separate listing. Match the version to your aircraft.

How do I know which version I have? Check the label on the module you are removing, or the aircraft's configuration. If in doubt, photograph the label and send it to us and we will match it.

My aircraft shows a LiDAR warning. Is the module bad? Often not. Clean the dome properly, inspect it for haze and scratches, check the mount, and reseat the connector first. A fouled or scratched dome produces the same warnings as a weak sensor.

Is the dome included? The module has its own domed window. The separate replacement dome and the LiDAR mount are listed on their own and are not included here.

Does the LiDAR avoid wires? Do not rely on it to. DJI states that linear obstacles such as wires must still be marked, and that the aircraft cannot automatically avoid moving objects.

Does it work at night? LiDAR does not depend on daylight, and the T100 can display LiDAR point clouds for takeoff, landing, and night operation. Range still varies with rain, fog, and obstacle material.

What is included? One LiDAR module with its integrated signal cable. No mount, separate dome, screws, or aircraft.

Can I fit it myself? Most operators can. Photograph the area first, keep the module pointing exactly as the old one did, route the cable as original, and confirm recognition and stable height hold before field work.

Does it need calibration? Confirm recognition, check the point-cloud display, and fly a low hover and a short terrain-following pass over familiar ground before returning to work.

Will it fit a T70P or T55? This module is matched for the T100 international version. For other aircraft, send us the label from your module and we will match it rather than guess.

Is there a service interval? No. The LiDAR is replaced when it is damaged or demonstrably faulty, not on a schedule.

What usually damages it? Strikes from branches and canopy, hard landings that also damage the mount, water entering through a cracked housing, and cable damage during transport.

How do I protect the new one? Rinse the dome after chemical days, clean it only with a lens cloth, and check the dome and mount in every pre-flight walk-around.

Why are the USA and international versions listed separately? Because they are sold as separate DJI versions, and a version mismatch is something to rule out rather than discover after installation. Separate listings mean the version you order is the version that ships.

Should I replace the dome at the same time? Only if it is hazed, scratched, or cracked. A clean, undamaged dome on a new module is fine; a damaged dome on a new module wastes the new module's range.
