The MQ135 Air Quality Sensor is a gas detection module designed to measure various air pollutants and provide an indication of overall air quality. Here’s a general description of the MQ135 Air Quality Sensor:

1. **Gas Detection:**
– The primary function of the MQ135 sensor is to detect the presence and concentration of different gases in the air.

2. **Target Gases:**
– MQ135 is sensitive to various gases, including but not limited to carbon dioxide (CO2), ammonia (NH3), methane (CH4), benzene (C6H6), and volatile organic compounds (VOCs).

3. **Semiconductor Technology:**
– It utilizes semiconductor technology to detect changes in the resistance of the sensor based on the concentration of gases in the air.

4. **Analog Output:**
– The sensor typically provides an analog voltage output that can be read by a microcontroller or other data acquisition system. The voltage level corresponds to the concentration of the detected gas.

5. **Air Quality Indication:**
– The sensor is often used to provide an indication of air quality, with higher concentrations of certain gases suggesting poorer air quality.

6. **Calibration:**
– Calibration may be required for accurate gas concentration measurements, as the sensor’s response can vary based on environmental factors.

7. **Detection Range:**
– The detection range of the MQ135 sensor varies for different gases, and it’s crucial to consult the datasheet for specific details.

8. **Applications:**
– Common applications include air quality monitoring in indoor environments, pollution detection in industrial settings, and integration into air purifiers or environmental monitoring systems.

9. **DIY Electronics:**
– The sensor is popular among hobbyists and DIY enthusiasts for projects related to air quality monitoring and environmental sensing.

10. **Compact Form Factor:**
– Typically designed in a compact form, making it easy to integrate into various electronic projects and systems.

11. **Ventilation Control:**
– In some applications, the MQ135 sensor can be used to control ventilation systems based on air quality measurements.

12. **Low Power Consumption:**
– MQ135 sensors are often designed with low power consumption, suitable for battery-operated devices or continuous monitoring applications.
