DescriptionThe MQ-135 Air Quality/Gas Detector Sensor Module is a widely used sensor module designed to detect a range of air pollutants and gases.
Here's a comprehensive overview of the MQ-135 sensor module:Purpose: The MQ-135 sensor module is designed to detect a variety of gases and air pollutants, making it suitable for air quality monitoring and environmental sensing applications.
Sensitivity: It exhibits varying sensitivity to gases like ammonia, nitrogen dioxide, benzene, carbon monoxide, and other harmful substances.
Principle: The sensor uses a semiconductor gas sensor where the resistance of the sensing material changes based on the concentration of gases in the air.
Features:Multi-Gas Detection: The MQ-135 module is capable of detecting various gases and pollutants, offering a wide range of applications.
Analog Output: The module typically provides an analog voltage output that can be correlated to the concentration of the detected gas.
Versatility: Due to its broad sensitivity to multiple gases, it's suitable for diverse air quality monitoring projects.
Affordability: The MQ-135 sensor module is cost-effective, making it a popular choice for hobbyists and environmental monitoring enthusiasts.
Applications:Indoor Air Quality: The MQ-4 sensor is widely used to detect methane leaks in households, industries, and commercial spaces. It's particularly useful in preventing potential explosions due to gas leaks.
Outdoor Air Quality: Deployed in outdoor environments to track pollution levels and understand the overall air quality.
Environmental Research: Employed in research projects to gather data on various gases and their concentrations.
Personal Projects: Popular among makers and DIY enthusiasts for building air quality monitoring devices.
Using the MQ-135:Powering the Sensor: The sensor usually requires a 5V DC power supply.
Calibration: Calibration might be necessary for accurate readings. This involves exposing the sensor to clean air to establish a baseline resistance value.
Reading Values: The analog output voltage from the MQ-135 module can be connected to an analog pin on a microcontroller (e.g., Arduino) to read the gas concentration. The specific gas being detected can be inferred from calibration data.
Considerations:Warm-Up Time: The sensor might require some time to stabilize before providing accurate readings.
Cross-Sensitivity: The MQ-135 sensor can exhibit cross-sensitivity to various gases, which might affect its accuracy in mixed gas environments.
Environmental Factors: Factors like temperature, humidity, and the presence of other gases can influence its performance. When integrating the MQ-135 Air Quality/Gas Detector Sensor Module into a project, proper calibration and accounting for potential cross-sensitivity are crucial for obtaining accurate and meaningful air quality readings.
