Assembled soldered board of RH Electronics Original Radiation Detector ver.3
with J305 NEW Geiger Muller Tube
pcb color: green or blue

The kit works as nuclear radiation detector. It compatible with Arduino UNO (or similar). It compatible with iPhone / iPad and fully supporting Geiger Bot application. To use the freeware application you only need a standard 4-strip iPhone cable to connect the board to your phone.

Technical specifications:

  • Geiger Tube PCB Compatibility: STS-5, SBM-20, J305, LND-712
  • Geiger Tube Voltage Compatibility: 400V or 500V tubes
  • Supply Voltage: 4.5-5.5V
  • Supply Current: 50uA-100uA (0.05mA-0.1mA) at background radiation
  • High Reliability up to 1mSv/h (1000uSv/h)
  • Sound and Visual Indication
  • Arduino, PIC, AVR, MSP430 Compatible (TTL Logic Level output to drive microcontroller count input)
  • TRRS Output Connector  for “Geiger Bot” iPad / iPhone or Android
  • Radiation Logger Compatible (require Arduino UNO or similar)
  • Dimensions: 120 x 50 mm

Benefits of original third edition:

  • Kit consumes less than 0.06mA at background, usually 0.05mA
  • Improved HV stability up to 1000uSv/h radiation load
  • More supported tubes, 400V and 500V range select
  • Tube over voltage protection, limiting HV spikes
  • Wide compatibility with different MCU for software developers
  • TRRS 3.5mm socket for direct connection to iPad / iPhone “Geiger Bot” or Android (this is not for headphones)
