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 RevSpace

Introduction. This page is about the MHZ19 CO 2 sensor and some experiments done with it.. This sensor gives a digital (serial) output of the CO 2 concentration in air, in partspermillion (ppm). It uses the optical measurement principle of measuring CO 2, which should be much more accurate than the inexpensive electrochemical sensors you can far as I know, the optical measurement ...

Nov 15, 2020· Modifications done to the second display: The only thing you must do for dual screens is change the bus address. Here I’ve also removed the redundant I2C pullups (R5R6, 4k7) and bridged out the 662k regulator which isn’t needed on a system. These changes usually bring sleepmode current on ″ OLEDs to about 2μA per screen. (or ~5μA ea. with the 662k regulator left in place)
