This session gives an overview of common sensor types used in smart building applications, especially for building HVAC control applications. Purposes of these sensors and theories of sensing principles or operations are discussed. Sensor types covered include temperature and humidity sensors, air velocity sensors, water flow meters, light level sensors, indoor air quality sensors (CO2, VOC, PM), and occupancy sensors. Toward the end of the session, the IoT sensor concept will be introduced, and several IoT sensor examples will be given to illustrate their capabilities and advantage over traditional sensors.
