MQ135 Gas Sensor CO2 Air Quality Sensor

MQ135 Gas Sensor is an Air Quality Sensor for detecting a wide range of gases, including CO2, NOx, alcohol, benzene, smoke and NH3. MQ135 Gas sensor use in Air Quality Control equipment and are suitable for detecting or measuring of NH3, NOx, Alcohol, Benzene, Smoke, CO2.

The MQ135 Gas Sensor is a low-cost, easy-to-use sensor that can use to detect a variety of harmful gases, including ammonia, nitrogen dioxide, sulfur dioxide, and benzene. It is a metal oxide semiconductor (MOS) sensor, which means that it uses a thin film of tin dioxide (SnO2) to detect the presence of gases.

Air Quality Sensor MQ135 is a low-cost, easy to use sensor that can use to measure the concentration of volatile organic compounds (VOCs) in the air. It is a metal oxide semiconductor (MOS) sensor, which means that it uses a thin film of tin dioxide (SnO2) to detect the presence of VOCs.

MQ135 sensor has a detection range of 10 to 1000 ppm (parts per million) of CO2, and a sensitivity of 10mV/ppm. This means that the sensor’s output voltage will increase by 10mV for every 1 ppm increase in the concentration of CO2 in the air.

The MQ135 gas sensor has an input voltage of 5V. This means that the sensor must be powered by a 5V source. The sensor also has an analog output pin that outputs a voltage that corresponds to the concentration of the gas being detected. The output voltage range of the analog output pin is 0 to 5V.

It is important to note that the MQ-135 gas sensor also requires a pre-heating period of 20 seconds before it can start detecting gases. This is because the sensor needs time to heat up to its operating temperature.
