Our take on the 24G MmWave HLK-LD2410C Human Presence Radar Sensor Motion Detection Module
The HLK-LD2410C is a 24GHz mmWave radar module that detects people who are present but still, not just people who move. It senses walking, micro-movement, sitting and lying bodies, and it keeps working through temperature, light and humidity changes. It also reads through plastic and other non-metal housings, so it can sit hidden inside a case. That makes it a step up from PIR sensors, which drop a person who stops moving, and it suits DIY presence detection for lights, HVAC and security. It is a bare module for makers, not a finished detector: you supply power, a controller and the logic.
- Detects stationary and micro-moving people, not only motion
- Sensing is not affected by temperature, light or humidity
- Works through non-metal housings without a cutout
- Farthest distance and per-gate sensitivity are configurable
- Reports motion, micro-motion and still presence separately

About the 24G MmWave HLK-LD2410C Human Presence Radar Sensor Motion Detection Module
The HLK-LD2410C is a 24G millimeter-wave human presence radar sensor module. It detects people in motion and also senses static, micro-moving, sitting, standing and lying human bodies that traditional solutions cannot identify.
Its sensing is not affected by temperature, brightness, humidity or light changes. It penetrates housings, so it can be hidden inside a product's shell without opening holes, which helps the product's appearance.
The farthest sensing distance and the sensitivity at each distance gate can be configured. The module supports multi-level parameter adjustment and can be used in many AIoT scenarios. Appearance and printed text may differ between batches, which does not affect use.

Questions and answers
- How is this different from a PIR motion sensor?
- PIR sensors react to moving heat and often drop a person who sits still. The LD2410C uses 24GHz radar and reports still and micro-moving presence too, so lights stay on while someone is seated.
- Can it be mounted behind a wall or case?
- It reads through plastic and other non-metal material, so it can sit inside an enclosure. Metal blocks the radar, and thin walls can let it sense people in the next room.
- What do I need to run it?
- It is a module only. You need a power supply and a microcontroller or host board, plus code to read its output and act on it.
- Can I change how far it detects?
- Yes. The farthest sensing distance and the sensitivity of each distance gate are configurable, so you can tune range and ignore far-off movement.
- Does it work in the dark or in changing light?
- Yes. It uses radar rather than light, so darkness, brightness changes and humidity do not affect detection.
- What is in the box?
- Three sensor modules. No cables, controller or power supply are included.
- Where can I buy the 24G MmWave HLK-LD2410C Human Presence Radar Sensor Motion Detection Module?
