MHZ19C CO2 Sensor • ThingPulse

Description. The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19C is the successor of the widely popular 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

20170630· The MHZ19 features a UART serial interface and 5V power supply and IO levels. This makes is easy to connect it directly to a Raspberry Pi or to a PC (If PC, you need to use an USB/serial converter (CMOS/TTL levels, not RS232 levels)).

The ESP32 board talks to the MHZ19B sensor via UART (another option is PWN). According to the datasheet, the sensor needs 5V voltage, therefore its V in pin is connected to the V in pin of the ESP32 board. When the board is powered via its USB port, the V in pin provides 5V. The other pins of the sensor are not used. The LEDs are connected to D13, D27 and D33 pins via current limiting ...

MHZ19 CO2 Sensor Home Assistant

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.
