The MQ-135 Air Quality Sensor Module is a popular gas-sensing component used in DIY electronics and air-monitoring projects. It detects a range of common gases and air-quality changes, making it a go-to choice for hobbyists, students, and makers building Arduino, Raspberry Pi, or microcontroller setups. Whether you are putting together a smart-home air monitor, a greenhouse sensor node, or a learning project, the MQ-135 gives you an easy, low-cost way to read air conditions.
Key features
- MQ-135 sensing element for general air-quality detection
- Compatible with Arduino, ESP32/ESP8266, and similar microcontroller boards
- Provides both analog and digital output for flexible wiring
- Compact module that is easy to mount on breadboards or project boards
- Simple to integrate into beginner and advanced electronics projects
Typical uses
- Indoor air-quality monitoring projects
- Smart-home and IoT sensor nodes
- Greenhouse and grow-room environment tracking
- Educational and student electronics experiments
- Hobbyist Arduino and Raspberry Pi builds
How to choose / tips
- Allow the sensor a warm-up period for more stable readings, as is standard with MQ-series sensors.
- Use the analog output with an ADC pin when you want relative readings; the digital pin works well for simple threshold alerts.
- Pair it with a stable power supply and clean wiring to reduce noise in your data.
