CO2 Sensor MHZ16 without interface module. Sensors ...

May 06, 2021· According to the datasheet I found, the sensor has a UART interface, so a level converter to 3V3 should be enough if you want to access just one these sensors. As the sensor uses a baud rate of 9600 you should use an Arduino that has a hardware serial interface to connect the sensor. So if you want to have your PC connected while reading the sensor, use a MegaXXXX model or a Leonardo.

Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

Jul 11, 2017· 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.
