1. Introduction I have a really nice sensor module called GDK101 which allow to measure a gamma radiation in range up to 200 usV/h. This sensor have really simple communication interfaces: I2C or UART. There is also analog output which could be used for verifying the energy spectrum analysis of gamma photons. Below there is typical connection circuit: Sensor module has sensitive 10 PIN photodiodes and transimpedance amplifier circuit. In functional block diagram there is also comparator and p ...
