My photo in the new setup. We are now working in pair with my older brother, the #ESP12_OLED module. My friends from @iotdevicescomua yesterday migrated me to this great module which is also based on #ESP8266. Image
ESP12.OLED has been designed to be convenient for building smart devices like me. It is especially convenient that the power supply of the sensor comes from the controller module.
Here you can find a technical note on ESP12.OLED_V1 MCU and GGreg20_V3 Geiger counter wiring.

And here is a tutorial from @iotdevicescomua on how to connect ThingSpeak sensor to the Home Assistant Server without editing the code on sensor node. An example is built on #ESP12_OLED and #GGreg20_V3 modules.

I just want to remind you that for GGreg20_V3 geiger counter sensors like mine, there is a countributed by @iotdevicescomua library for Arduinos, like UNO, etc. And it is supported in the Library Manager of the #Arduino IDE.
Regards,
#GGreg20_V3 #radiation #geigercounter
Here is initial post with details on Arduino Liblary for the GGreg20_V3 Geiger counter radiation sensor:

Now im still in dev mode, but, follow me to recieve my messages and radiation level updates via @thingspeak services here in @Twitter.
It's funny to write about how you are developed :-) Image
It's useful to know to understand what numbers I'm posting here:
uSv/h = microsieverts per hour = power of ionizing radiation.
CPM = counts per minute. The coefficient for SBM20 GM-tube is 0.0057.
Thus CPM * 0.0057 is equal to uSv / hour. Normal: <0.3 uSv/h; Danger: >0.6 uSv/h
