MHZ19C CO2 Sensor • ThingPulse

The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19 C is the successor of the widely popular MHZ19 B. See below for a comparison. The MHZ19C 400~2000ppm CO2 sensor has builtin temperature compensation and communicates over UART and PWM with the host controller.

Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

· MHZ19 python datalogger test program. The simple test program opens the UART com port serial0 and tries to read CO 2 measurement values from the CO 2 sensor every minute. The program prints every measurement to the screen and logs timestamped measurements to a csv formatted file, which is given the current date and time as the filename. Improvements to the program are welcome 🙂

As the communication with the MHZ19 is done using UART, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the MHZ19 and the tx_pin connected to the RX Pin of the MHZ19 (it’s switched because the TX/RX labels are from the perspective of the MHZ19). Additionally, you need to set the baud rate to 9600.

CO2Sensor MHZ19B Unsinnsbasis

The MHZ19 is a small nondispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should increase ventilation.
