About

ESPGeiger connects your Geiger counter to your network. It works with common pulse-based counters as well as a number of models that report over a serial link.

Once your counter is connected, you can watch radiation trends as they happen, keep a record over time, and share your readings with community monitoring networks if you wish.

• Internet Connectivity: Get your Geiger counter online, so its readings are available beyond the device itself.
• Integrated Web Interface: View the latest readings and change settings from your web browser, no app required.
• Recording and Reporting: ESPGeiger records your counter’s readings over time, so you can follow radiation trends and spot any change in your background level.
• Data Sharing: ESPGeiger can send your readings to a number of platforms. Some popular options:
  • MQTT: Publish your readings to an MQTT broker to feed them into other smart home devices or your own applications.
  • Home Assistant: Add your counter’s readings to your Home Assistant dashboard, alongside the rest of your home’s sensors.
  • radmon.org: Submit your data to radmon.org, a community platform where enthusiasts and researchers pool their readings into a worldwide monitoring effort.
