11-07-2017· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.
I’ve never really messed with a Raspberry Pi before and it was a fun experience getting it set up. I did need to buy a micro-SD card from Target to boot the Raspberry Pi operating system from. I also wasted time trying to find an SD card reader for a couple hours before realizing that my Dell XPS 13 laptop has a built-in microSD card reader.
01-01-2018· The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm and two relays which can be triggered on a low CO2 (Generally above 1000 ppm) normally ...
