I heard that electronic enthusiasts will make a Geiger counter.

Facing the increasingly complex world environment and electronic waste,

I will also imitate it.

The foreigner version looks like this more advanced one, with its own parameter calibration and WIFI remote check meter. 

In particular, the boost circuit cleverly uses the 555 circuit, which greatly reduces the production cost. 

The original post used the Wemos D1 mini board module and I directly integrated it into a board.

  This Geiger counter software has two versions, GC-01 and GC-20. 

I have packaged GC-01 into an ARDUINO library and can be directly compiled and uploaded with Arduino, or I can use the compiled firmware to upload directly with the ESP8266 download tool. 

  For the internal structure during production, I used 18650 so the shell is a bit thicker.
