Some Theory

Low Cost Air Quality Sensor

Characteristics

• Sensitivity
• Proven Accuracy
• Location
• Unit? Range of gases, particulates and environmental conditions
• Secure
• Credibility
• Installation and Operation
• Remote Management
• High quality

Particle Phase

Larger particles (>0.1 μm)

Possible sensor measurement issues:

• Particle detection capability – transport of particles to sensor, sensor sensitivity
  • Some use a passive means to move air through sensing region; others have a fan.
• Signal translation to concentration estimate

Gas Phase

Metal oxide sensors

Possible sensor measurement issues:

• Interfering gases in mixture
• Measurement artifact due to temperature and humidity
• Eventual failure of sensor

Electrochemical sensors

Possible sensor measurement issues:

• Interfering gases in mixture
• Measurement artifact due to temperature and humidity
• Eventual failure of sensor

Photoionization sensors

Possible sensor measurement issues:

• Baseline drift
• Eventual failure of sensor based on lamp lifetime.
