The ADuCM3029_demo_cn0536 project provides a solution to measure radiation levels using most of Geiger-Muller tube sensors available in the market. It uses the precision programmable oscillator LTC6906 to generate high voltage output for the tube and the LTC1540 nano power comparator to set and regulate it. With the LTC1441 ultralow power dual comparator the Geiger pulse is translated to logic level 3V or 5V and the LTC6994 robust built in delay block timer chip will generate a Geiger clicking sound to a regular buzzer.
Also, onboard LEDs are used to indicate radiation levels and information about the counts per minute and microSieverts per minute are sent over UART or over the internet through MQTT.
A sample python code is available to plot MQTT data into a graph with a radiation threshold.
The following is a list of items needed in order to replicate this demo.
