AZ7798 CO2 meter - Tasmota

The AZ7798 CO 2 Meter/Datalogger appears to be made by AZ Instrument, but other branded versions exist.. The CO 2 meter is already provided with a PC interface in the form of a logic-level (3V3) serial port, accessible through a stereo jack on the back. The Wemos D1 Mini is connected to this serial port instead, and the PC interface is no longer available.

Sonoff Basic and/or Dual with MQ2 Gas Sensor · Issue #1304 ...

2017-12-05· Plan A was to connect the sensor directly to the Sonoff Basic, which would be ideal as its close to the gas source to be monitored. I'm completely unsure how to enable the analog input and initial research I've read talks about some serious soldering and my soldering skills aren't that great. Plus, I can't seem to find any pictures detailing how to expose the analog pin.
