Geiger counter settings

[lavAzza]

Please help to connect Geiger counter to NodeMCU v3 with ESPEasy Mega.
I use noname Geiger counter with 5v logic, logic convertor and NodeMCU v3.
Schema
Geiger counter ----- Converter ----- NodeMCU
GND ------------------ GND | GND --- GND
5V -------------------- 5V | 3,3V ------ 3,3V
VIN ------------------- A4 | B4 --------- D3
There is no any counts in Device page.
I tryed different Debounce Time and Mode Type settings.
Geiger counter is work fine with Arduino Uno.

[lavAzza]

Can anybody help?

[grovkillen]

Have you tried any other mode except "LOW"?

[TD-er]

100 msec debounce time does sound a bit long.
I can imagine the pulses of this Geiger counter are short, maybe a bit too short for the ESP to detect properly.

You could add a flipflop in between the ESP and the Geiger counter. Then every blip will trigger a status switch on the flipflop output, which will result in a up- or low-level period which is a lot longer.
Every detected level change reflects a count.

hi,

i have the same project : connect a cheap Geiger counter to Domoticz with a wemos and Espeasy on it .

Did you finally found a solution to connect them together ? and want to share it ?

thanks a lot

Belgo

[belgo]

hi to all,

Finally i dont find anything already done and then i'll make it myself

i use a Wemos ( ESP 8266) , a cheap geiger counter with J305 tube and a LCD 4 X 20 chars.

the ESP send data to Domoticz with JSON http instruction.

here the result .

i'll try to take a little time to make a schematics and share my code ..

there is some little bugs to correct , i am not a good coder

but someone else could probably help me to fine tune it

see you soon

I get similar functionality using ESPEasy with counter plugin and single gpio. Data is uploaded to mqtt broker every minute, then processed in Node-Red and visualised in Grafana.

[dudule]

Bonjour Belgo,

J'ai acheté le même matériel que vous pour remonter les infos du compteur geiger vers Domoticz et évidement utilisé votre code et votre schéma de raccordement (merci d'avoir partagé).
Pouvez-vous m'expliquer maintenant ce qu'il faut faire du coté Domoticz ?
Merci pour votre patience !
Cordialement,
Dudule.

Can you share the settings U used? get it working with the small scripts I can find on the internet but not with ESPeasy or Tasmota.

[chemmex]

Hi, below is my pulse counter plugin screen. My geiger cirquit produce short positive pulses, no debounce, and they just get registered by the plugin.

Hi,

I managed to get working the geiger kit RadiationD-v1.1(Cajoe) under EspEasy. I used the plugin "Generic - Pulse counter" with the following configuration:

espeasy-geiger-1.png (72.07 KiB) Viewed 18121 times

Note that the "Mode Type" should be Rising (or Falling) to avoid counting twice each event. Also I fixed the inteval to 10 seconds. This value can be decreased to obtain values more frequently or increased if you prefer to measure values less frequently.
Then I define a dummy device using the "Generic - Dummy Device" plugin to allocate the variables which will contain the measurements in cpm (counts per minute):

espeasy-geiger-2.png (72.93 KiB) Viewed 18121 times

Finally I assign the values to the variables in the dummy device using rules:

espeasy-geiger-3.png (88.91 KiB) Viewed 18121 times

The factor 6 comes from the fact that we are using cpm, but measuring at 10 seconds, then we have to multiply by 6 to get the counts per minute. Actually this factor is calculated as 60/interval. If for example we choose 5 seconds for the interval, then the factor would be 12. Also there are two quantities which should give the same value: Total/Time, which the total number of counts divided by the time that the board is on (%unixtime%), and also the average value of the instant measurements. The use of the variable %unixtime" is not a good choice when the time is larger, since this variable cannot accommodate big numbers. I just included it for checking purposes.

Cheers!

Jose.

Great
Just curious, what is your occupation, or where do you live that a Geiger counter is usable?

[jbarea]

I live in Chile. I am planning to make an indoor environment station which includes a dust sensor, a CO2 sensor, temperature and humidity sensors and radioactivity detector, just for fun. The geiger counter can be purchase here:
https://es.aliexpress.com/item/32822477320.html and the data can be sent to https://radmon.org/index.php. I am physicist, by the way.

[TD-er]

Ah didn't know that site.
Nice idea to have a global map for radioactivity.
If we ever get another Chernobyl or Fukushima, or some government tries to do experiments, we can 'track' them.

I'll think I will order one just for the fun of it.

[Ath]

Could you post the rules in a [ code ] [ /code ] block (without the spaces), so it is a bit easier to copy them without typos

Yes!! That's the idea. There aren't commercial nuclear plants in Chile, but there are in Argentina or Brazil, and any leak could travel by air anywhere.

[TD-er]

Yep can imagine one may not believe everything the Brazilian government tells via the official news media, with the current president.
Measuring is knowing.... as long as you know what you're measuring. (In Dutch: Meten is weten als je weet wat je meet)

I still remember in '86 that Tsjernobyl caused even more concerns by the fact the information was held back at first.

[chemmex]

We are installing Espeasy-based geiger counters in Belarus where we have twice the trouble: 25% of the territory contaminated by remains of Chernobyl, and a freshly built nuclear power plant which nobody beleives is safe. It is always good to know the truth even if someone goes panic.

[bubastic]

A great solution.
But can someone tell me how to make the RadSens counter work with ESPEasy?

But can someone tell me how to make the RadSens counter work with ESPEasy?

That is already requested here and on the list of plugins to be implemented, but not started yet

[Ath]

@bubastic I've created PR #5104 for P163 - Counter - RadSens I2C radiation counter. A GH Actions run is working on the binaries. Currently only available for ESP32 MAX builds (requires 8 MB or 16 MB ESP32, ESP32-s3 or ESP32-c6 unit), but I'm working on a solution to make it available for ESP8266 4MB builds and ESP32 4MB builds too.
For downloading from that Actions run you'll need a (free) Github account.

Edit: Updated GH Actions run link to current latest

[Ath]

We decided to not add this plugin in any default build for ESP8266, as that platform is practically feature-frozen for ESPEasy.
For those that need an ESP8266 build, a `Custom` build can be created, as documented here (start at the top for setting things up properly, and continue until you reach the chapter where a custom build using Custom.h is described).

For ESP32 this plugin is, besides the MAX builds, also available in the Collection G builds.

[Ath]

A great solution.
But can someone tell me how to make the RadSens counter work with ESPEasy?

@bubastic
Not sure if you managed to create a Custom ESPEasy build (assuming ESP8266), but if not, I can do that for you, if you specify what other plugins you also need to be included. (I'll start with the regular 'Custom' build included in the default set of builds).

This is about the ESPEasy firmware, so you could try a test build with the plugin for the geiger counter included.

For example the test builds here: https://github.com/letscontrolit/ESPEas ... 0376956716

[jmdlcar]

Can I just use Arduino IDE to install geiger_counter.ino? I'm not sure.

I been using Geiger counter cajoe for years then other day I seen this so I wanted to add this display so this is all new to me I have all the parts now so now I going to build it then add the code.

[TD-er]

You do know what ESPEasy is?
It is a complete firmware aimed at people who don't know (yet) how to program and/or know about electronics but still would like to connect sensors to microcontrollers and start doing something with the data.

There are over 160 different 'plugins' to support various hardware and in the link I gave you is a build which does include support for this Geiger counter.

This support forum is about this ESPEasy firmware.

[jmdlcar]

You do know what ESPEasy is?

No I don't know where to start. I might only use it 1 time and it just to get Geiger Counter to have a display screen.

[Ath]

You do know what ESPEasy is?

No I don't know where to start. I might only use it 1 time and it just to get Geiger Counter to have a display screen.

This thread is in 2 parts:
- First 23 messages are about a Geiger counter board that provides a pulse output that can be read/counted by ESPEasy using the Pulsecounter plugin. Another user 'belgo' has provided some independent Arduino code, 4.5 years ago, that has nothing to do with ESPEasy.
- From message #24 on this is (also) about another Geiger counter board, RadSens, that uses an I2C interface to provide the counter data. I've added a new plugin for ESPEasy that can use the I2C interface to retrieve the counter values.

Depending on the Geiger counter board you are using you can use ESPEasy to get the counts, and also present those counts on a display, as these are also supported by ESPEasy. But the solution for that is not documented exhaustively, you'll have to dive in the ESPEasy documentation to complete that. We can provide some guidance with the use of ESPEasy, if needed, after you've studied the documentation over here: https://espeasy.readthedocs.io/ (there's a lot to read there...)
ESPEasy runs on ESP8266 and several models of ESP32 boards, not on Arduino boards.

If you want to use the hardware setup and Arduino code by 'belgo', then you'll have to dive into using the Arduino IDE, uploading the code provided to your Arduino board, and connecting the display and Geiger counter as shown in the schematics. We won't be able to help you there, but there's other help available from the Arduino community, you'll have to google for that.

[bubastic]

I have been successfully using RadSens for over a week now as part of ESPEasy and confirm that no problems have been noticed so far.
