How to measure a gas meter with a reed sensor and a KC868-A8 board - pacitzu - 01-02-2025
I would like to measure a gas meter with a reed sensor and a KC868-A8 board.
I tried to connect it to the dry contacts of the KC868-A8 (pcb v 1.5) but it seems that the pulses that are too fast are not read.
Is it correct to connect the reed sensor directly between GND and a free GPIO S1,S2,S3 or S4 to avoid losing these pulses?
Furthermore, since the KC868-A8 board and the gas meter are very far away (10 meters) and the gas meter is located outside the house, it is recommended to isolate the signals with a board with a 3.3v/12v optocoupler.
Thanks in advance

yes, you can test with S1,S2,S3,S4 , these gpio have connected with ESP32 pin directly.
