We love this handheld Geiger counter purely for the excitement of trying to track down radioactive sources like old clock and watch faces. However, it’s easy to forget that for some areas a radiation detector is an essential bit of safety kit that can help keep you healthy.
In many parts of the world, foraging for found foodstuffs is widely enjoyed, but in areas (such as the Ukraine) there is the added complication of checking if fruits, berries or mushrooms contain a radioactive dose. Not only is this dangerous to someones health, there are heavy fines and even prison sentences if you introduce contaminated foodstuffs into the foodchain.
The GGreg20_V3 Ionizing radiation detector is supplied as a pre-built module and has a buzzer on board for that familiar Geiger counter pulsing. It’s designed to be used in conjunction with any microcontroller that can be used to log the pulses. Pretty much all popular microcontroller families can do this and we certainly know that Arduino, Trinkets, ESP32 and more have lots of examples out there to count pulses presented at a GPIO pin.
It can run on a range of voltages from 1 cell through to 3 cell and weighs a diminutive 30 grams. It’s highly likely you could build a full logging, battery powered, pocket scale device that wouldn’t weigh you down on your next foraging adventure.
