Description:
The MQ-135 Air Quality/Gas Detector Sensor Module is designed for detecting a variety of harmful gases, including Ammonia (NH3), Sulphide (H2S), Benzene steam, and smoke. It offers a reliable solution for monitoring air quality and detecting hazardous gas levels. The sensor provides analog (0-5V) and TTL digital outputs, which make it easy to interface with Arduino and other microcontrollers. The sensor’s sensitivity can be adjusted, and it has fast response and recovery times, making it ideal for applications like indoor air quality monitoring, smoke detection, and toxic gas monitoring.
High Sensitivity: Detects Ammonia, Sulphide, Benzene steam, smoke, and other harmful gases.
Dual Output Signals: Analog (0-5V) and TTL digital outputs for easy integration with microcontrollers.
Adjustable Sensitivity: Onboard potentiometer allows you to adjust the sensitivity for precise measurements.
Fast Response: Quick detection of gas concentrations with rapid response and recovery.
Signal Indicator: Provides visual signal output that increases as the gas concentration rises.
Low Cost and Reliable: Affordable and reliable for a wide range of applications.
Applications: Suitable for air quality monitoring, harmful gas detection, and smoke detection.
Operating Voltage: 5V DC
Output Types: Analog output (0-5V) and Digital output (TTL)
