Specification Brand : WSDMAVIS BulletPoint1 : The item has visual and sound indication of the radiation and can be used as detector of dangerous radiation levels or radioactive materials in your environment. BulletPoint2 : Geiger tube parameters:diameter:Φ10±0.5mm; Total length: 90±2mm;Starting voltage: Recommended operating voltage: 380V; Minimum plateau length: 80V; Maximum plateau slope: 10%/80V; Extreme operating voltage: 550V; The maximum count rate: 25 times / min; Life: > 1 x 10^9 pulse;Medium temperature: -40 ~ 55 ℃; Size:108x63x20mm BulletPoint3 : System parameters:5V power supply, or 1.5V 3x battery; 1.2V 4x battery, current: 12mA - 30mA,for the detection of 20mR/h ~ 120mR/h of gamma rays and 100 ~ 1800 off variables / points / cm 2 of the soft beta ray.Sound and light alarm;Interrupt the output interface, through this interface can be connected to the microcontroller and then displayed on the LCD. BulletPoint4 : Supports most of the Geiger tube: M4011, STS-5, SBM20, J305, etc. the 330~600V operating voltage of the Geiger tube can be supported).Support the computer (PC) data acquisition, Matlab analysis and processing. BulletPoint5 : 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: INT and GND.
