CO2 sensor MHZ19

The MHZ19 is a sensor that uses the nondispersed infrared principle to detect CO2 in the air. It has builtin temperature compensation and high sensitivity to gas detection, and therefore has extremely accurate readings, and its outputs are on UART and PWM. It consumes little electricity and has a long service life. • Model: MHZ19• Voltage: • Response time: less than 60s ...

MHZ19 CO2 sensor

MHZ19 CO2 sensor driver. Description. The MHZ19 is a CO2 sensor. Measurements are provided in parts per million (ppm) over UART and PWM. The ppm value ranges from 0 (theoretically) to 2000 or 5000, depending on the sensor settings. In UART mode, additional commands are available to configure the sensor. Note that the sensor requires considerable time before accurate measurements are …
