SCD40 CO2 Module

It does what it says, a bit over priced and my needed a huge offset

Aside from the shipping issues unrelated to the sensor, the tiny sensor is a bit overpriced for what it is, specially since we already over paid for the main sensor. The two data points that the sensor provides were widely off and needed to have an offset (talking -30 degrees F) applied. Thankfully Apollo has provided the variables to do that. For the cost I expected a better result.

It's bulky, especially with the ceiling mount

Don't want this into my ceiling, it's to big and does not look beautiful. Too nerdy. Because of that I didn't test the hardware itself out. Love the idea, but design is definitely not great.
