Where please? What model.
- en-us 7y agoI'm not the OP, but I use this one with similar results: https://www.amazon.com/gp/aw/d/B01FYWU2IS https://www.amazon.com/gp/aw/d/B01FYWU2IS One of these days I'm going to have to rig up something to start the house fan when the CO2 goes above 800 ppm and I think you'd need a different sensor with a realtime output port for something like that.
- bumby 7y agoIf you want a reference on setting this up to meet industry standards on demand controlled ventilation practices see ASHRAE 62.1 and 62.2 standards
- ip26 7y agoDirect feedback is cool, but a simple schedule is really easy & reliable. Even occupancy detection isn't all that critical- nobody wants to come home to a stuffy house, and most people's schedules are very predictable. These days IoT is so widespread that something like a $25 WeMo smart outlet is hard to beat. Hard wired is "best" but a million times more hassle and more expensive.

- jeffnappi 7y agoI own this one as well, it's supposed to be one of the more accurate models available for the price
- elitan 7y agoWhere did you get the information about this model being more accurate than other models in the same price range?
- jeffnappi 7y agoThis was the article that gave me that impression iirc - https://medium.com/@dhh/air-quality-matters-but-dont-trust-foobot-on-it-e2df4234a776 https://medium.com/@dhh/air-quality-matters-but-dont-trust-f...
