Geiger counter

By Ben Everard. Posted

Here’s a simple but useful project: an internet-connected Geiger counter. Its creator, Dmytro Panin, lives in Kyiv, Ukraine, not far from the site of the Chornobyl nuclear reactor and its associated fallout zone. Understandably, Dmytro wants to keep an eye on local radiation levels.
The build consists of an M4011 Geiger sensor connected to a Raspberry Pi Pico W, which sends the readings to a server every few hours. Dmytro’s also included a 128 × 64 pixel OLED screen to display readings, for those rare occasions when he isn’t glued to the internet.
