Introduction
prototype

Interesting Fact
This data logger records radioactivity registered by the Smart Geiger Sensor (need to buy separately) in terms of sound clicks. This app works better than the manufacturer's app that seems to read a higher than usual readings probably because that app is meant to be used to read ambient radiation. Our app is better for targeted radioactivity sources.
