ESP8266 Arduino sketch + hardware documentation was created by nu3e
I wrote a simple ESP8266 Arduino sketch to count interrupts from a RH Electronics Geiger Counter DIY Kit 3.0 and periodically upload the CPM value to radmon.org via WiFi. The GitHub repository includes commented source code, a photo of the complete counter, a wiring diagram, a schematic diagram, and documentation.

This is a very inexpensive way to join a counter to radmon.org, as ESP8266 NodeMCU modules sell for about $5 USD on eBay.

Hi John. Nice project and very well presented code and repo. Many thanks for sharing. I have been meaning to get a ESP8266 to play with for a while and they seem to be well used in the Home Assistant ecosystem. I've recently purchased a Raspberry Pi Pico W and hope to do something IOT/HA with that too. All the best, Richard (station rjelbert)

I have just had confirmation from another user that this code works fine. Thanks nu3e!

I am using your code with an aliexpress geiger Counter board. This needed one modification, namely replacing R19 with a 100nF ceramic capacitor. Thanks.

Hi John
Thank you for a nice project.
It works fine when I use my iPhone as wifi access point but when I use my in house wifi I do not get connection.
(instead I get a "seudo" IP address 169.254.29.19)
Wondering if it is the DHCP not accepting the ESP8266?
Do you have any experience with this issue?
