Setting up the MH-Z14A CO2 sensor with Raspberry Pi ...

2020-05-17· So I bought an an MH-Z14A sensor to get CO2-levels at home, by attaching it to a Raspberry Pi 3. Indoor CO2-levels have pretty large impact on sleep and concentration. Usually measured in ppm (parts per million), the desired values are below 1000ppm. CO2 levels and effects source. PPM Effects; 250-400: normal outdoor air level : 400 - 1000: indoor, good airflow: 1000-2000: …

CO2 Sensor MH-Z16 without interface module. - Sensors ...

2021-05-06· According to the datasheet I found, the sensor has a UART interface, so a level converter to 3V3 should be enough if you want to access just one these sensors. As the sensor uses a baud rate of 9600 you should use an Arduino that has a hardware serial interface to connect the sensor. So if you want to have your PC connected while reading the sensor, use a MegaXXXX model or a Leonardo.
