Specifications:
5V power supply, or 3x 1.5V battery; 4x 1.2V battery current: 12mA - 30mA
For detecting 20mR / h ~ 120mR / h of γ-rays and 100 to 1800 off variable / min · cm 2 soft β rays used.
Sound and light alarm
Interrupt output interface, can then be displayed on the LCD connected to the microcontroller via this interface.
Ardunio compatible
Size: 118 x63 mm

The PCB has 3 pins for communication with MCU: INT, GND, 5V. You can power up the kit from 5V Arduino board directly. Or, if you use batteries for Geiger Kit, you have to connect only 2 pins to Arduino: INT and GND.
There is many different application you can use this kit, especially if you are software developer. The board send 500 uS high-low-high interrupts to Arduino. We offer 2 simple sketches as an example, please modify it for your needs.
Actually its possible to use this kit with any other microcontroller, not only Arduino boards because it has the same principles, but if you are beginner it will be easy to start with Arduino.
