MP135 Air Pollution Gas Sensor DIP-4
The MP135 Air Pollution Gas Sensor, housed in a DIP-4 package, is an essential tool for detecting and measuring a wide variety of pollutants in the air. Known for its broad detection range, fast response time, and high sensitivity, this sensor offers reliable performance for air quality monitoring. It can detect volatile organic compounds (VOCs), carbon dioxide, carbon monoxide, and other harmful gases, providing critical data for environmental assessments and management. With the insights from the MP135 sensor, individuals, communities, and regulatory authorities can take informed actions to improve air quality and protect public health. In comparison to similar sensors like the MQ135, the MP135 excels in accuracy, reliability, and ease of integration, making it a top choice for air quality monitoring applications.
Features:
Gas Detection: The MP135 is capable of detecting multiple gases, including ammonia (NH3), nitrogen dioxide (NO2), and benzene (C6H6), among others.
Sensitivity: The sensor’s sensitivity might vary based on the specific gas being detected.
Analog Output: It typically provides an analog output voltage that changes in response to the concentration of the detected gas.
Operating Voltage: The sensor module might require a specific operating voltage, typically around 5V.
Calibration: Like many gas sensors, proper calibration is essential for accurate readings.
Selective Gas Detection: If your application requires the detection of specific gases such as ammonia (NH3), nitrogen dioxide (NO2), or benzene (C6H6), the MP135 might be a better choice due to its ability to detect these gases.
Targeted Environmental Monitoring: If your project focuses on monitoring and controlling certain pollutants like industrial gases or specific toxic compounds, the MP135’s selectivity could be advantageous.
Air Quality in Specific Environments: If you need to assess air quality in specific environments where the presence of certain gases is more critical, such as industrial settings or areas near pollution sources, the MP135’s targeted detection capabilities might be useful.

Frequently Asked Questions
What gases can the MP135 detect?
The MP135 is optimized to detect volatile organic compounds (VOCs), carbon dioxide (CO₂), carbon monoxide (CO) and a variety of other hazardous gases found in indoor and outdoor environments.
How do I interface the MP135 with a microcontroller?
Connect the sensor’s VCC and GND to your power supply (usually 5 V), then route the analog output pin to an ADC channel on your microcontroller. Use a load resistor as specified in the datasheet and read voltage variations to infer gas concentration.
What is the recommended warm-up time before taking readings?
Allow the MP135 sensor to warm up for approximately 1–2 minutes after power-up. This ensures stable baseline readings and consistent sensitivity for accurate air quality measurements.
