esphome-geiger-counter

A half-assed attempt to put my geiger counter on Home Assistant.

My geiger counter from RH Electronics sends data over serial/UART.

  • Wired/UART logs don't work. Use wireless logs.
  • Only uSv is sent.

Wiring

You'll need to use a logic level shifter to convert the 5v signals to 3.3v.

Configuration

The status LEDs are configured using a ranging approach. The green LED turns on when the uSv reading is below the configured safe_level. When the uSv reading is between safe_level and warning_level, the yellow LED turns on. All readings above warning_level trigger the red LED.
