Experiences with an MHZ19 CO2 sensor | Erland Lewin ...

My experiences with the MHZ19 NDIR CO2 sensor Warning: I just destroyed my MHZ19 sensor when soldering, I was changing connectors with lead free solder, iron set to 380 C. I had to heat for a little while to remove the old header. Now the sensor only gives a very low value, both on PWM and serial output. Before destroying the device, I was getting strange values around 900 ppm when I should ...

Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

20170711· Introduction: In this article we will do a simple functional test of the MHZ19 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.

Carbon Dioxide Sensor MHZ19b Part 1 Hardware design ...

20190610· Carbon Dioxide Sensor MHZ19b Part 1 Hardware design. Some time ago I have purchased online carbon dioxide (CO2) sensor module MHZ19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 4001000ppm.

20180309· Pinout. The module has lots of pins on it, most of which are duplicates. I just stuck to the main pitch 2 x 6 connector on the right. Note that the pin numbering on the board reflects the evolution of various connectors added through versions of the boards, and is therefore a bit odd. First Use My first experiment was just to powerup the board (5V to pin1, GND to pin 2) with a ...
