MQ135 Air Quality Detection Sensor

MQ135 Air Quality Detection Sensor: A Comprehensive Overview

The MQ135 Air Quality Detection Sensor is a versatile and reliable tool designed to measure the concentration of various gases in the air, including ammonia, alcohol, benzene, smoke, and carbon dioxide. Its ability to detect a broad range of gases makes it an essential component in applications like air quality monitoring, gas leakage detection, and environmental control systems.

Key Features

1. Wide Detection Range: The MQ135 sensor is capable of detecting gases in the range of 10 to 1000 ppm (parts per million). This broad detection range allows it to be used in various environments, from residential areas to industrial settings. Whether monitoring indoor air quality or detecting harmful gas leaks, the MQ135 provides accurate and reliable readings.
2. Operating Voltage: The sensor operates at a standard 5V DC, making it compatible with most microcontrollers and development boards, such as Arduino and Raspberry Pi. Its low power requirement ensures that it can be easily integrated into existing systems without the need for additional power supplies.
3. Analog Output: The MQ135 provides an analog output voltage that varies in proportion to the concentration of detected gases. This output can be easily read by an analog-to-digital converter (ADC) in a microcontroller, allowing for real-time monitoring and analysis of air quality. The sensor’s sensitivity can be adjusted via an onboard potentiometer, providing flexibility in various applications.
4. Preheat Time: To achieve accurate readings, the MQ135 sensor requires a preheat time of over 24 hours. This is necessary to stabilize the sensor’s internal components and ensure reliable gas detection. Once the sensor has been properly preheated, it can provide consistent and accurate measurements over extended periods.
5. Compact Design: The MQ135 sensor features a compact and lightweight design, making it easy to integrate into various projects. Its small size allows it to be used in portable air quality monitoring devices, as well as in larger, stationary systems. Despite its compact form factor, the sensor offers robust performance and durability, making it suitable for both amateur and professional use.
