Gas Sensor Module (MQ-135)

The MQ-135 gas sensor is designed to detect a wide range of gases such as ammonia, nitrogen oxides, benzene, smoke, and CO2 in the air, making it suitable for air quality monitoring and industrial safety applications.

Specifications:

• Gas Detection: Detects ammonia (NH3), nitrogen oxides (NOx), benzene (C6H6), smoke, and CO2 concentrations in the air
• Sensitivity: Adjustable sensitivity for different gas concentrations
• Detection Range: Typically, 10 to 1,000 ppm for NH3, 10 to 1,000 ppm for NOx, 10 to 1,000 ppm for C6H6, and 10 to 10,000 ppm for CO2
• Response Time: Rapid response to changes in gas concentration

Power:

• Supply Voltage: Operates at 5V DC
• Heating Element: Requires a heating element for sensor activation, typically consumes around 350mW

Input and Output:

• Input: Air containing the target gases (NH3, NOx, C6H6, CO2) to be detected
• Output: Analog voltage signal that varies with gas concentration

Physical Characteristics:

• Dimensions: Compact and suitable for integration into air quality monitoring devices
• Material: Housed in a metal or plastic casing for durability
• Mounting: Designed for easy installation in industrial and residential environments

Additional Features:

• High Sensitivity: Detects low concentrations of gases effectively
• LED Indicator: Provides visual indication of gas detection
• Applications: Used in air quality monitors, environmental monitoring systems, and safety devices for detecting harmful gases.

The MQ-135 sensor contributes to maintaining indoor air quality and ensuring safety by promptly detecting potentially hazardous gases. For specific operational details and calibration guidelines, consulting the sensor’s datasheet or manufacturer’s specifications is recommended.
