It features a tin dioxide sensor that detects harmful gases within 10-1000ppm, providing both TTL digital and analog voltage outputs. With fast response times, low power consumption, and a built-in power indicator, it offers reliable, real-time hazardous gas monitoring for home and environmental safety. ## 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 ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07L73VTTY | | Date First Available | 7 January 2019 | | Is Discontinued By Manufacturer | No | | Item Model Number | 430578031 | | Manufacturer | Ximimark | | Product Dimensions | 2 x 3.2 x 2.2 cm; 18 g | ## Product Details - **Brand:** Ximimark - **Colour:** Silver - **Power source:** Corded Electric - **Product dimensions:** 20D x 32W x 22H millimeters - **Style:** Modern ## Images ![Ximimark 3Pcs MQ135 MQ-135 Air Quality Sensor Hazardous Gas Detection Module for Arduino - Image 1](https://m.media-amazon.com/images/I/61GZzj82ZzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value. *by on Reviewed in the United States 29 January 2026* Okay for the price. Was looking for something different but handy to have. ### ⭐⭐⭐⭐⭐ They work as advertised *by on Reviewed in the United States 29 May 2024* 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. ### ⭐⭐⭐⭐ Not bad, it works *by on Reviewed in the United States 25 November 2025* 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. ## Frequently Bought Together - Ximimark 3Pcs MQ135 MQ-135 Air Quality Sensor Hazardous Gas Detection Module for Arduino - HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/356564083-ximimark-3pcs-mq135-mq-135-air-quality-sensor-hazardous-gas](https://www.desertcart.tn/products/356564083-ximimark-3pcs-mq135-mq-135-air-quality-sensor-hazardous-gas) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-29*
