Infrared CO2 Sensor Module (Model: MHZ19B)

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, precision …


MHZ19 CO_2 and Temperature Sensor — ESPHome

MHZ19 CO_2 and Temperature Sensor¶. The mhz19 sensor platform allows you to use MHZ19 CO_2 and temperature sensors () with ESPHome.. MHZ19 CO_2 and Temperature Sensor. ¶ As the communication with the MHZ19 is done using UART, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the MHZ19 and the tx_pin connected to the RX Pin of the MHZ19 …
