Arduino Based Geiger Shield

This is an Arduino-based Geiger counter shield that is easy to upload data to the internet and also interchange tubes. It is open source and Arduino-based, so it will be easy to hack to other interesting applications.

The radiation board has two main parts, the power circuit and the signal circuit. The power part is used to provide the voltage necessary for the tube and the signal circuit is use to adapt the pulses output from the tube and connect it to the input of the microcontroller. Once the tube is powered, we can receive the pulses in the microcontroller and count them, then with an easy calculation we can get the value of radiation. The need of an open, net-spreaded visualization of the real level of radioactivity was heavily felt by the community. The usage of this sensor board along with the affordable and easy to use Arduino platform helps people to get radiation values from specific places.

A Geiger tube is a remarkably simple device, but getting the part can be a fairly expensive proposition. It has already tested and verified a number of tubes from which is very helpful.
