Radioactivity has always been a fascinating phenomenon for anyone concerned in physics, and due to this we’ve featured many radioactivity-related initiatives on these pages over time. More not too way back nonetheless, fears of nuclear disaster have prompted many hackers to look into environmental radiation monitoring. [Malte] was a form of in search of to enhance the radiation monitor on his local weather station, nonetheless found the alternatives for wi-fi geiger counters a bit restricted.
So he decided to assemble himself his private Wifi and LoRa applicable environmental radiation monitor. Like most such initiatives it’s based on the ever current Soviet-made SBM-20 GM tube, although the design moreover helps the Chinese J305βγ model. In each case, the tube’s working voltage is generated by a discrete-transistor based oscillator which boosts the board’s 5 V present to spherical 400 V with the help of an inductor and a voltage multiplier.
The tube’s output signal is reworked into clear digital pulses to be counted by each an ESP32 or a Moteino R6, counting on the collection of wi-fi protocol. The ESP might make its data on the market via an internet interface using its WiFi interface, whereas the Moteino can speak via LoRa and sends out its data using MQTT. The ensuing data is a counts-per-minute price which can be reworked into an equal dose in Sievert using a simple conversion formulation.
All design info may be discovered on [Malte]’s website online, along with a PCB construction that neatly fits inside customary waterproof enclosures. Getting additional radiation screens out throughout the self-discipline can solely be a superb issue, as we found as soon as we tried to detect a radiation accident using community-sourced data once more in 2019. Don’t like WiFi or LoRa? There’s a great deal of totally different strategies to connect your GM tubes to the net.
