HLK-LD2410B FMCW 24G 24GHz Smart Human Presence Status Sensing Radar Heartbeat Sensitivity Mini Sensor Module High Detection

Product Information

This sensor is natively supported in Home Assistant and can be easily integrated with ESP32 and ESPHome. The LD2410B module is a high-sensitivity human presence detector that uses Frequency-Modulated Continuous-Wave (FMCW) or somewhere you can see it as mmWave technology to detect humans. This USB cable will be used to power up the sensor, because the sensor is so tiny and there are no USB ports on it this is the only way. You can simply attach the standard Dupont connectors from the ESP32 Board to the sensor and you are done. ld2410 : id : my_ld2410 api : services : - service : set_ld2410_bluetooth_password variables : password : string then : - bluetooth_password.

If coded correctly, you can turn it into a reliable presence detection device without false positive or negative triggers. Future Plans: To address the "noise" issue, I'm currently testing a multi-sensor setup combining the LD2410 sensor with a PIR sensor. We recommend that you always read the product labels, warnings, and directions before using any product. With the current smart presence sensors available in the home automation market, comes the inevitable challenge of actually picking the right presence sensor for your smart home. LD2410B is a high-sensitivity 24GHz human presence status sensing module developed by Hilink Electronics.

Hmmm, I don’t have any issues with any other Bluetooth devices and it does seem to be a common issue on the LD2410 threads so perhaps there’s a bad batch or it happens to work really well with your Bluetooth stick?

The Apollo MSR-1 is based on the 24GHz Hi-Link HLK-LD2410b mmWave radar sensor, which is also used in many other devices of the same type (e. move_energy ( Optional, int): When in engineering mode, the move energy of the gate, otherwise unknown. still_energy ( Optional, int): When in engineering mode, the still energy of the gate, otherwise unknown. Once you have all the components and tools ready, you can start to assemble this DIY presence sensor.There are additional package vars you can define to name the 2nd and 3rd sensor differently, and to connect with a changed password on the ld2410b devices (you should use the app HLKRadarTool to change the password). This module gives real-time detection results and it is perfect for indoor use, but it is also rated that can work from -40 to +85 degrees Celsius, so I guess if you waterproof it somehow it can be used outside as well. A higher percentage reading indicates increased speed; the faster the movement, the higher the percentage displayed.
