Review on 🌡️ Continuous Temperature Monitoring with Relative Humidity Integration by Justin Miller

I bought this after reading the latest research that CO2 levels above 900ppm reduce our ability to think by 30% or more, however this will certainly affect me when playing guitar or video games as I get older. My goal was to keep the room at around 600ppm and not spend too much money on heating and air conditioning. It controls a small window fan (very small and very quiet, commonly used to cool computer cases - Noctua 200mm). For more information see this guide: http://www.instructables.com/On-Demand-CO2-Exhaust-Fan/ The device does exactly what I want: - In human mode, the ambient light sensor is ignored, yes we produce CO2 during sleep mode. - With an average of 600ppm and a zone set at 50ppm (minimum allowed), it turns on at 625, turns off at 575 and turns on again when it reaches 625. - 15ft sensor cable is great, didn't want it to be near the fan or in its way. Programming took a few minutes, the menu is finicky with a very short wait time, but only needs to be set once. I put it next to my other newly calibrated CO2 meter to test and it was within 10ppm.
