The MQ-135 is an easy-to-use gas sensor that detects a wide range of harmful gases in the air, making it ideal for air-quality monitors and safety projects. It senses ammonia (NH3), carbon dioxide (CO2), benzene, smoke, and other pollutants, giving both analog and digital output.
Connect it to an Arduino, ESP32, or Raspberry Pi to build indoor air-quality monitors, pollution-sensing IoT devices, and smart-home safety alerts.
Key features:
- Detects CO2, ammonia, benzene, smoke and other harmful gases
- Both analog and digital output with adjustable sensitivity
- Works with Arduino, ESP32 and Raspberry Pi
- On-board potentiometer to set the detection threshold
- Operating voltage 5V — simple 4-pin connection
