“VERSION 1.1
This project provides a very affordable (25) IoT for Radioactivity long term monitoring using the MQTT transmission protocol widely use in IoT environment. It can be integrated into Home automation applications or Node-RED environments.
C-GM Device Features :
beta, gamma and X-ray radiation’s counter
Max CPM : 65535 (430 µSv/h)
Support GM tubes such as SBM-20/19, STS-5 (CTC-5), SI-29-BG, SBT-9/11A, SI-180G, LND-712/7312, etc.
400V GM tube High Voltage
Ethernet connection for control and data communication
Static IP address support only
The interface is basic and made of a LED and one button.
Returns current CPM and µSv/h, Max and Average values
LED flash on discharges and report failure (steady or fast blinks)
External 6V DC pack power (e.g. 6V/1A DC pack available from Amazon, eBay, Banggood, etc.)
Low cost, few components
OPTIONAL : The module can be power from an external 5-9V DC pack or using PoE (power over Ethernet). The PoE voltage must be within the range 5-9V.”
