GGLABS GRAD Dual tube Geiger-Muller counter SHIELD for ARDUINO SBM-20 Radiation

Description

GGLABS GRAD
Ultra low power dual tube Geiger-Muller counter shield for Arduino. Uses common SBM-20, STS-5 and J305 tubes.
Other 400V tubes can also be used, but mechanical fit might not be perfect.
Consumes less than 0.1mA @ 5V. The double tube feature can be used to increase the sensitivity (by using two tubes of the same type), to increase the range by using tubes with different sensitivities.
Simple interfacing to Arduino. Uses only 2 pins and power. Open source design.
Open source SW for a complete USB logger is available for download.
Geiger tube(s) and Arduino not included in the listing.
We recommend SBM-20 or J305 tubes and Arduino Uno.
The board is also available with preinstalled and tested J305 tubes at
