01/05/2018· The ESP32 with CO2 sensor MHZ19B (v2) and LCD display from Nokia 5110. There are few ways to read data from the sensor: from PWM output; from serial port; from V0 analog output (not checked) This project uses the serial port (works more stable). Connect the sensor, when data are read from the sensor''s serial port.
