Détecteur Geiger-Müller à double tube (extension pour Arduino)
Capteur très sensible pour très faible rayonnement
With two tubes for increased sensitivity, this Geiger-Müller tube shield can turn your Arduino Uno into an instrument for measuring and recording nuclear radiation. It can even be combined with a Dragino shield for LoRa-connectivity. Collect radiation data in the “field” — and get access to it from all over the world!
