This is a kind of quality Geiger counter, it will automatically connects to the Internet and uploads data to the server through WIFI or WIFI hotspot of mobilephone. With OLED display, you can see the CPM(counter per minute) value clearly. Support computer(upper-computer) data collection, MATLAB analysis and processing, send and collect source code of program. Support most Geiger tubes with 330 to 600V operating voltage, such as M4011, STS-5, SBM20, 305, etc. You can have a try.

Features:
Automatically connects to the Internet and uploads data to the server through WIFI or WIFI hotspot of mobilephone.
OLED display, you can see the CPM(counter per minute) value clearly.
Using IFTTT sending message and warning.
Plug to use, it can directly detecting nuclear radiation after plug in powersupply.
Support most Geiger tubes with 330 to 600V operating voltage, such as M4011, STS-5, SBM20, 305, etc.
Support computer(upper-computer) data collection, MATLAB analysis and processing, send and collect source code of program.
Compatible with Arduino, we recommended arduino-uno-R3 or others with 5V and external interrupt INT.
It can be used to detect Y rays of 20mR/h-120mRh and soft β rays of 100-1800 variable/min·cm2.
Equipped with sound and light alarm function.
Interrupt the output interface, through this interface can be connected to the microcontroller and then displayed on the LCD display.
