MICS 6814 sensor use without I2C on Arduino compatible boards

Dear all,

I try to interface a MICS 6814 based board like this one, without I2C support, with an arduino compatible TTGO V2 ESP32 board. I looked for a library supporting it, but I couldn’t find anything except code for the I2C interfaced sensor.

Did anybody used that sensor before and know how I may use it?

Thanks for your help.

No, not at all. I fear I bought some useless boards :confused:

Indeed this is an analog sensor board : you need to read voltage(s) using ADC pins and then to calculate the actual values from that, which is not simple. And there seems to be a need for a calibration process every time you move the sensor to a new place.

A quick search on github lead me to this repository where someone implemented a version for raspberry pi - if you know what you are doing you might start from that.
