The Hardhack Muon Detector project has created a muon detector kit based on a coincidence detection circuit using twin Geiger–Müller tubes.

The output is a 3.3V pulse, between 2.6 to 8 uS. A regular ESP based microcontroller board can be used to count or perform some other action when registering a pulse.

This repository contains code for ESPHome to program a Heltec Wireless Stick Lite V3 for connecting this sensor to the rest of the IoT world.

Interface Board Examples

Heltec Wireless Stick Lite V3, using ESPHome

The Heltec Wireless Stick Lite V3 is based on the esp32-s3 microprocessor which includes Wireless and Bluetooth. The board also contains a LoRa transceiver for communication outside of Wifi range.

Files

esphome/esp32s3-muon-detector-led.yaml

Configuration file and program for the muon detector. This version supports external LED strip light (WS2812 based).

esphome/esp32s3-muon-detector-v2.yaml

Configuration file and program for the muon detector with support for dual input channels (GPIO1, GPIO2) for separate measurement of muon and background counts.

esphome/secrets.yaml

Contains Wifi, API, Over the Air (OTA) update details. Edit these to what you are using.

This build requires that the ESPHome build system is installed and available.
