## Overview

The Ximimark MQ135 Air Quality Sensor Module is a compact, dual-output gas detector designed for Arduino projects. It accurately senses harmful gases like ammonia, benzene, and sulfur within 10-1000ppm, delivering both TTL digital and analog signals. With fast response times, low power consumption, and a durable sensor element, it’s ideal for proactive environmental monitoring in smart homes or DIY air quality setups.

## Description

The gas-sensitive material used in the MQ135 gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is a polluting gas in the environment, the conductivity in the sensor increases with the concentration of polluted gas in the air. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit. Specifications: Size:32* 20* 22mm (L*W*H) Input voltage: DC5V Power consumption ( current ): 150mA DO output: TTL digital 0 and 1 ( 0.1 and 5V) AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V Note: After the sensor is powered , needs to warm up around 20S, measured data was stable, heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal. The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully! Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness. We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution. Package Includes: 3Pcs

Review: You have to burn or oxidize the sensor in before it will work properly. Which means powering it for about 8 hours and letting it settle for an hour before getting accurate readings from it.
Review: Worked for me. Tested to see if it functions. I can make it detect and clean air it shows too. They work, price is fair to a little high, easy to use.

## Features

- High quality dual panel design with power indicator and TTL signal output indication.
- TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port).
- Analog output with increasing concentration, the higher the concentration, the higher the voltage.
- A hazardous gas detection apparatus for the family, the environment. Suitable for ammonia, aromatic compounds, sulfur, benzene vapor, and other gases harmful gas detection. Gas-sensitive element test concentration range: 10 to 1000ppm.
- Long service life, stable and reliable. Has fast response and recovery features.
