I’ve seen some DIY arduino kits but I’m really curious if you could build or purchase a home geiger counter that integrates with HA. Anyone have any experience with this?

i bought one, needed some mods to get it working. put esphome on it. works a treat. [Geiger]

that is just some grafics with the duration of the data?

the device puts out CPM. The Geiger tube has a specific micro Sieverts per hour calibration depending on the type of tube. Just added ESP32 and ESP home to count and transmit the data. Here is my ESPH code. esphome: name: esp-geiger01 esp32: board: esp32dev framework: type: arduino # …

I know that my question is about the graphs… I know how to do them with time but…. How do you do the top limit? I assume that it’s the security point isn’t it?

Realized I didn’t actually post my source code. It’s mostly the Brian Gauger example code with MQTT communication added. I used an STM32 “Blue Pill” because I already had one set up on a breadboard with a W5500 module however any Arduino will work if you adjust the library used (from Ethernet_STM t…

Hi. I have the CAJOE version of the Radiation detector. I calibrated it, and it powers up fine, and beeps and has VIN drop low on an oscilloscope when it clicks from background radition. I have an Olimex ESP32-POE-ISO unit that is powered by POE (the final home of this is on my roof, and thanks to…

There are no ideas. Everything looks correct at first glance.

Geiger counter with HA integration?
