Description:
Geiger tube parameters: Technical parameters diameter: Φ10±0.5mm Total length: 90±2mm Starting voltage: < 350V 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:108x63x20mmInfos: click here!
Features: 1) 5V power supply, or 1.5V 3x battery; 1.2V 4x battery, current: 30mA - 12mA 2) for the detection of 20mR/h ~ 120mR/h of gamma rays and 100 ~ 1800 off variables / points / cm 2 of the soft beta ray. 3) sound and light alarm 4) interrupt the output interface, through this interface can be connected to the microcontroller and then displayed on the LCD.
5) Ardunio compatible 6) supports most of the Geiger tube: M4011, STS-5, SBM20, J305, etc. (the 330~600V operating voltage of the Geiger tube can be supported). 7) support the computer (PC) data acquisition, Matlab analysis and processing Detection of nuclear radiation work (copy the following link to the browser to watch): Http://v.youku.com/v_show/id_XNzI3MTU2NzQ0.html Customers using our Geiger counter to record the video: Http://v.youku.com/v_show/id_XOTE4ODIyNTIw.html
Compatible with : (recommended UNO R3 , or any other arbitrary with 5V and external interrupt INT) Internet can be downloaded: SPI example for Radiation Logger Logger Radiation can be used as the host computer software to build radiation monitoring station. Package included: 1 x Assembled Radiation system 1 x GM Tube 1 x Power supply cable 1 x Battery Holder (without batteries) 3 x Jumper Wires 4 x Nuts 1 x Acrylic cover
Go unlucky and received a unit from a lower quality batch. No support for the ICs, missing resistor meaning the power LED does not work, badly connected resistor, and even an inductance mounted SMD style because the leads were cut too short. The solder joints have not been heated enough and the solder did not penetrate in the vias. The board is pretty dirty (flux and solder residues that could short tracks).
Otherwise, the device works and is quite cheap. It comes with a lot of accessories which is useful.
This is a good geiger counter at cheaper price, perfect to connect with a ESP or arduino module to make a portable radioactivity meter. The board show the particle detected via a buzzer a red led and via TTL pulse output. The module can be connected to battery pack (primary or NI-Mh cell) or directly powered from an Arduino or ESP module via 5V pin. Useful to continuos meter the enviromental radioactivity.
A good Geiger counter +++
