Intelligent Infrared CO2 Module (Model: MH Z19B)

Z19. B NDIR CO2 Module 1. Profile . 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 ...

Winsen Infrared CO2 Module MHZ19 / MHZ19B / MHZ14 serial "api" implementation. MHZ19 Datasheet. MHZ19B Datasheet. MHZ14 Dahasheet. This crates proposes two kinds of functions: functions for parsing response read from the uart; functions to create command payload to send to the sensor though the uart.


MHZ19 RevSpace

0x79: ABC logic on/off (ABC = automatic baseline correction) 0x99: Sensor detection range setting, this command can be used to set the measurement range ( 02000ppm or 05000ppm) It appears that these commands work on the MHZ19 too, although with a little different command layout. Specifically, the range for command 0x99 is not put into ...
