The ESP32 board talks to the MH-Z19B sensor via UART (another option is PWN). According to the datasheet, the sensor needs 5V voltage, therefore its V in pin is connected to the V in pin of the ESP32 board. When the board is powered via its USB port, the V in pin provides 5V. The other pins of the sensor are not used. The LEDs are connected to D13, D27 and D33 pins via current limiting ...

2019-06-10· Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm. Higher levels lead to various negative effects like a feeling of “bad air” and so on. The concentration of 2000 ...
