Webb6 maj 2024 · As the sensor is driven by 3.3V I doubt that it accepts a 5V signal on it's I/O pins (at least the datasheet says maximum 3.3V). So you have to use a level converter between the sensor and the Mega (which is running on 5V). You might destroy the sensor if you connect 5V directly to it's pins. WebbDatasheet MH-Z14A is a NDIR sensor. Make sure power supply range is stable and fit, or sensor might output very low number (e.g: 410ppm) At beginning (around 30 seconds), the sensor response is not correct. When doing zero point calibration, put MH-Z14A sensor in outdoor that CO2 level is 400ppm.
