MQ 135 Air Quality Sensor

- The MQ-135 is a gas sensor module used for monitoring indoor air quality, detecting harmful gases like ammonia (NH₃), nitrogen oxides (NOx), benzene, alcohol, and smoke, offering both analog (voltage) and digital (threshold) outputs for microcontrollers like Arduino or Raspberry Pi. It works by changing its electrical conductivity as pollutant gas concentration rises, requiring a pre-heat time and a 5V supply, making it great for DIY environmental monitoring, alarms, and IoT projects.
- Analog output voltage: 0V to 5V
- Digital output voltage: 0V or 5V (TTL Logic)
