MHZ19 Buffer size: A transmission from the MHZ19 is 9 bytes long: 1 Start byte 1 Sensor number 2 bytes data 4 bytes padding 1 byte checksum. The start byte is not stored because it is not used in the checksum calculation. define MHZ19_BUF_SIZE 8 MHZ19 Timeout in milliseconds: 20 ms gives a decent margin on top of the UART transmission time. The datasheet does not specify any timings …

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. Note: the new version MHZ19B requires the VIN to be ...
