Reliable presence detection

I've tested several modules and this Hi-Link version is very stable. No random disconnects or erratic behavior. The ability to distinguish between moving and static targets is a game changer for bathroom lighting.

Superior to standard PIR

Finally a solution that knows someone is actually in the room even if they aren't walking around. I use this to control office lighting and it has saved energy by not turning off lights while I'm reading at my desk.

Good value for money

Works as advertised. The documentation could be slightly more detailed regarding the configuration commands, but there are plenty of community examples online. Detection is fast and accurate.

Perfect for Smart Home Automation

This sensor works flawlessly with my ESP32 project. It detects even slight breathing movements when I'm sitting still, which older PIR sensors missed completely. Setup was straightforward using the UART interface.

Great sensitivity, needs calibration

The detection range is impressive up to 6 meters in my hallway. Had to spend some time tweaking the sensitivity thresholds to avoid false positives from moving curtains, but once configured, it's very reliable.

Compact and powerful

The form factor is tiny, making it easy to hide inside light fixtures. The 24GHz millimeter wave technology really makes a difference in accuracy compared to infrared sensors. Highly recommended for DIYers.

5 FAQ

Q: What is the maximum detection distance in an open space?

A: In ideal open conditions, the sensor can detect human presence up to 8 meters. However, walls, furniture, and interference may reduce this effective range slightly.

Q: Is this module compatible with Arduino?

A: Absolutely. Since it communicates via UART (TTL logic), you can easily connect it to any Arduino board with serial capabilities using the TX/RX pins.

Q: Can I adjust the sensitivity zones?

A: Yes, you can configure detection ranges and sensitivity levels by sending specific configuration commands over the UART interface using the official protocol documentation.

Q: Does it require an external antenna?

A: No, the LD2410C comes with an integrated PCB antenna, so no external components are needed for basic operation.

Q: Can this sensor detect a person sleeping without any movement?

A: Yes, the LD2410C uses millimeter wave radar to detect micro-movements such as chest expansion from breathing, allowing it to sense static human presence effectively.
