13/04/2020· The sensor specs say it can draw up to 150ma, which is WAY MORE than the Arduino 5 volt can supply. Try connecting the sensor directly to a 5 volt supply.
MHZ19B NDIR infrared gas module is a common type, small size sensor, using nondispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, nonoxygen dependent and long life. Builtin temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology ...
09/10/2016· 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 …
