New Station Kenley Surrey

Wow, you've done a really nice job documenting your geiger kit project. It's all good but I especially like your use of 8 digit display modules - I will copy that
My first geiger kit was also a clone that I upgraded, but, interestingly, it lead me to the source - https://sites.google.com/site/diygeigercounter/home

Thanks Juzzie. I have just uploaded to code to the site so it is just about completed.
I have tried to credit the DIYGeigerCounter web site as much as possible. The owner has let me cut and paste bits of info from his site to my site making it a lot quicker to build.

Please let me know if you find any errors (I know my coding is bad) or any further info you need if you add the 7 segment displays.
If you don't use a PIR you will need to take the "infraredSw" parts out or hold that pin high or the display will flash on and off randomly.

I have now added the 7 segment display dimming direct from the remote control number buttons.
When not in a setup menu pressing number buttons 0 to 9 sets the display brightness.

As soon a number from 0 to 9 is pressed the secondary count LED illuminates and the CPM Pk display is blanked and replaced by the brightness number pressed on the remote.

Once the button is released the secondary count LED goes out, the display is set to that brightness value and CPM Pk is displayed again. The current value is then displayed on the LCD display.

See looped animation below showing brightness being set from 6 to 1.



I have updated the code on my site here Arduino Geiger Counter

I have now added rain detection along with temperature and humidity to my Geiger counter so really its now more of an environment monitor.
Temperature and Humidity are standard add-on documented in the GK-WiFi kit using a DHT22 sensor that I have mounted outside of my case.
Rain detection uses the spare ESP8266 GPIO4 pin and a small addition to the GK_WiFi sketch.

Rain detection uses a Kemo Rain Sensor

As soon as rain touches the surface of the sensor a relay is operated. The relay contact connects 3.3v to GPIO4 pin and this changes the Rain reading from 0 (no rain) to 1 raining.
The rain sensor also starts heating up the sensor surface so as soon as rain stops the surface dries out and the relay releases changing the rain reading to 0.

I have reformatted the OLED display slightly to show all the sensor reading in 2 columns.


The reading is also sent to ThingSpeak.
I wonder if my background readings will increase when it rains? I should be able to make a chart to compare the 2 readings together.
I still need to connect the rain sensor up and will do this when my SBM19 tube arrives as I plan to mount it outdoors near the rain sensor.

Another use for this function could be adding intrusion detection on your external Geiger Muller Tube case. Just wire in a micro switch to operate when the case is opened and configure ThingSpeak to send you an alert.

Nice to see all you've been doing with the kit.
You do great work.

Your documentation is amazing too!

I must say, Brett, this is the first home-brew thing I've seen with OLED, LCD, 7-segment LED and illuminated button all together. And it looks nice too. By your map charts, it seems that about 3 days ago you made a change causing your counts to jump to near 120 CPM, with daily variations typical of outdoor stations. If this is your new normal background level, then you should increase the Warn and Alert levels in Radlog Professional (on the Radmon tab). As it stands, your station is showing yellow/ red on the map.

P.S. How about adding a CRT?
