MHZ19 CO_2 and Temperature Sensor — 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 (it’s switched because the TX/RX labels are from the perspective of the MHZ19). Additionally, you need to set the baud rate to 9600.
