An LND7317 tube has been connected through the Theremino Geiger sensor to an ESP8266 (Tasmota firmware). Every minute, a node.js app asks for the current count though MQTT, makes the CPM to uSv/h conversion, and finally sends it to ThingSpeak. Enjoy! :-)

Data collection of background Radiation count/Dose, Temperature, Humidity, Atmospheric pressure (Installed outdoor since Dec 22 2017) Using GK-Radmon + v2.1

This is a Rad-Mon+ Geiger Counter located at the Cly Institute for Radio Research, directly West of 3 Mile Island.
