DFRobot Gravity - Geiger Counter Module Ionizing Radiation Detector - DFRobot SEN0463

The Geiger counter allows you to detect ionizing radiation in the surrounding environment. The DFRobot module from the Gravity series is based on a Geiger M4011 meter lamp , which supports voltages from 380 V to 450 V, measures the background of approx. 25 CPM with a coefficient of 153.8 CPM / (μSv / h) . The module is supplied with the voltage from 3.3 V to 5 V. The maximum measurement range is up to 1200 μSv / h (theoretically). There is a digital signal at the output, it goes low when a pulse is detected.
