# esphome-geiger-counter
|
|
|
|
*A half-assed attempt to put my geiger counter on Home Assistant.*
|
|
|
|
My [geiger counter from RH Electronics](https://www.rhelectronics.store/arduino-ide-geiger-counter-dosimeter-diy-kit-with-lcd) 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.
|
|
|
|
|
|
