Building Automation System Input Sensors

Learn how some common building automation system input sensors work to control the environment in commercial buildings. See how the following building control sensors work.
Current Sensor for Energy Monitoring, Dew Point sensors on a Chilled Beam, CO sensor in a Garage Exhaust System, CO2 sensor for the control of ventilation, Occupancy sensor for lighting control, Differential Pressure Sensor for VFD control of pump speed, Duct Static Pressure transmitter for VFD control of a Fan, etc.
