Build Human Presence Sensor with ESP8266, LD2410 and ESPHome, Integrate into Home Assistant.
The photo above is my cheap human presence sensor with ESP8266 and LD2410C mmWave radar sensor. It costs about RM 27—ESP8266-RM 9.90 and LD2410C-RM 17.61. This is my first time using ESPHome and LD2410. The LD2410C mmWave radio sensor module comes with Bluetooth connectivity, and Home Assistant has an integration for this sensor module. We can power the LD2410C and directly integrate the sensor module into Home Assistant via Bluetooth....
