I just got me one of these awesome [Sparkfun gas sensor breakouts](https://shop.pimoroni.com/products/gas-sensor-breakout with the MQ-7 carbon monoxide sensor) and I would love to connect it to my Enviro+ to give me an additional point of data for my “home weather station”.
It has four pins “H1, A1, GND and B1”
The enviro+ has 3V3, SDA, SCL, #4, GND, A3V3, GND, and 5V
obviously, I connect GND to GND, but I’m a little confused as to what I do with the other three pins.
Any suggestions? (also if anyone has any python example code on how to actually get the data from the sensor, I would really appreciate it). Cheers!
