Motion sensor/detector mmWave HLK-LD2410B (with BLE bluetooth)

Product information:

The LD2410B is a highly sensitive 24GHz human presence status sensor developed by Hi-link. Its working principle is to use FMCW frequency modulated continuous wave to detect human targets in the set space. Combined with radar signal processing and precise human body detection algorithms, it realizes highly sensitive detection of human presence status and can identify human bodies in motion and at rest. And additional information such as the distance to the target can be calculated.

This product is mainly used indoors to detect whether there is a moving or micro-moving human body in the space, and output the detection results in real time.
The farthest detection distance can be 5 meters and the distance resolution is 0.75 meters.
With a visual configuration tool (bluetooth) that allows you to easily configure the sensing distance range, sensing sensitivity in different intervals and unattended delay time, etc., to adapt to various specific application needs.

Support GPIO output, UART output and Bluetooth.

The Bluetooth version allows you to set the sensor from your smart phone using the HLKRadartool.

Among other things, use it on an ESP32 in combination with ESPHome (see website link).
