Using an LD2410C for presence and move detection.

The sensor must be able to detect presence / distance and move for advanced automations. For this we will use Hi-Link LD2410C.

We need :

Wemos D1 Mini –> Find it !

LD2410C –> Find It !

Dupont cables –> Find it !

Wiring of LD2410c to Wemos D1 Mini :

5V -> VCC / GND ->GND / TX -> RX / RX -> TX

You need to add this code to your ESPHome firmware :

uart:
  id: ld2410_uart
  tx_pin: GPIO1
  rx_pin: GPIO3
  baud_rate: 256000
  parity: NONE
  stop_bits: 1

 
ld2410:
  uart_id: ld2410_uart
  throttle: 1500ms
  id: ld2410_comp

Pay attention you MUST disconnect LD2410C power to be able to flash ESP if it’s wired to it.

After restart you will be able to use the device and its values for any automation. You can adjust setting like speed using Hi-Link app on your smartphone and bluetooth, and see values for adjusting thresholds.
