Geiger counter settings

#1 Post by lavAzza » 23 May 2018, 22:41

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.

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.
