Gas (Co2) sensors on batteries
-
@korttoma I got mine a month ago from China. I think it can be used with batteries, but it has to be something like 18650 3000mAh to last longer.
@alexsh1 I was not planing on using it on batteries'. I now have an MQ-2 sensor in the ventilation fresh air intake to detect smoke but it has proven to be unreliable so I thought id try the MH-Z14 instead. Sometimes smoke comes in through the ventilation an then I want it to turn off automatically.

I received my MH-Z14 yesterday hocked it up on a breadboard to test it and it seems to be working as expected. Now I need a more permanent setup so I can test and compare to a Netatmo indoor module. I may add an SI7021 to the same node.
