UNIQUE High Voltage Module for 400V Geiger Tube
with 2 independent channels with pulse output for each tube
can be used for Coincidence Muon Cosmic Ray Detection with a micro-controller
excellent long-term HV stability, allows to use up to 2 GM tubes
allows to measure HV safely with a micro-controller ADC
Will be shipped covered with Epoxy on electronic components
Input Voltage: 5V DC
Output Voltage: 390V-420V
Signal Pulse Outputs: 2 channels SIG1 and SIG2
Analog Output A0 for ADC
Supported Microcontrollers: Arduino, Raspberry Pi, PIC, AVR, ESP, (for 3.3V logic by default)
please see scope screenshot in the item's photos to see signal shape
Because of the high energy, muons can trigger two Geiger tubes with a sheet of lead between them almost simultaneously whereas normal background radiation and other particles will only trigger the two detectors randomly. Background gamma radiation is not energetic enough to pass through both tubes (and the lead) and trigger them both. Thus, when you get a coincident detection, it is very certain to be a muon.
If you want to monitor high voltage on tubes with microcontroller ADC you can use A0 module output. It has about 2000mV DC for 400V.
