MHZ19 Timeout in milliseconds: 20 ms gives a decent margin on top of the UART transmission time. The datasheet does not specify any timings beside the UART baud rate. A single byte takes 10 bits effectively: a start bit, 8 bits data and stop bit. 9 bytes are transmitted, thus 10 bits * 9 / 9600bps = ms. define MHZ19_TIMEOUT_READ 20 define MHZ19_TIMEOUT_CMD (MHZ19_TIMEOUT_READ * 5) MH ...

20161009· I have a MHZ19 CO2 sensor, according the datasheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 05000ppm, and via PWM I should have readings between 02000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I''m realized …

According to the Winsen MHZ19B datasheet, only 2000 and 5000 PPM models exist. (This was based on version of the datasheet. Version does list a 10000 PPM model.) The fake sensors may be suitable depending on what you use them for, but they show severe jitter of up to 50 PPM (peak to peak) and they often don''t properly do the ABC. My ...

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