The ESP32 board talks to the MHZ19B 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 ...
