Can we have a trigger when Gravity Geiger detects a disintegration ?

I don't know if this forum is so active, but I'd need to know if I can use the Gravity Geiger module (https://wiki.dfrobot.com/SKU_SEN0463_Gravity_Geiger_Counter_Module) for getting each disintegration pulse in real time counted on my arduino
I mean..
For each pulse, I want to know what is “written” on the digital pin. I guess the digital pin goes to +5V on detection and goes back to 0V when nothing happen.
If it does that, I can do what I want on the arduino.
Thanks if someone answers.
Hi there, thanks. I'm more interested in logging pulses than counting them over time. So if I can intercept these pulses, I'll be totally ok.
I'll need to find a option to connect this one to arduino and to raspbery too.
I'll order a couple. Can we have a private messaging for discussing ?
Julien.Bayle Hello,
The SEN0463 Geiger Counter Module uses pulses to measure the radiation intensity, the voltage goes from 0 to VCC, if you are using Arduino UNO or mega it is most likely peaked at 5V. However, the measured radiation strength is in units of CPM, and the background radiation is around 25 counts per minute. This means that in most indoor or outdoor environments, the module will send at least 25 times high signals every minute (25 pulses) and when there is a radioactive source present the counts may go well beyond this value. The library for this module uses the interrupt function to capture the pulses due to this nature.
