MiCS-5524 (CO, Alcohol and VOC Gas Sensor)

Suitable Uses:

• Carbon Monoxide Detection
• Natural Gas Leak Detection
• Monitoring Air Quality
• Early Fire Detection
• Breathalyzer (alcohol detection)
• Only 4 Pins: 5V: Power, GND: Ground
• Ao: Analog Output (0V to 5V: as the amount of detected gases increases, voltage increases) 
• En: Output Enable (to turn off the sensor for power consumption, send a HIGH 5V signal)

Detection ranges:

• Carbon Monoxide CO: approx 1 to 1000 ppm
• Ammonia: approx 1 to 500 ppm
• Ethanol: approx 10 to 500 ppm
• H2: approx 1 – 1000 ppm
• Methane: approx 1000++ ppm
• Propane: approx 1000++ ppm
• Iso-Butane: approx 1000++ ppm
