Oct 05, 2018· mh-z14a (co2) You can find the MH-Z14A on eBay pretty cheap. While not the nicest CO2 sensor (I like the COZIR Ambient ) they do have the benefit of being really cheap (for a true CO2 sensor) and when compared with better sensors are accurate enough for this kind of project.
Feb 17, 2019· MH-Z14 is the cheapest CO2 sensor I was able to find. I costs about $19 and comes in few variants: MH-Z14 and MH-Z14A. Also it can measure up to 1000 ppm, up to 2000 ppm or up to 5000 ppm. However the range does not matter in practice, as it is possible to switch between them using UART. The device interfaces are quite flexible for such a cheap ...
