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.
