The National Renewable Energy Laboratory (NREL) has developed and made available for license the image processing occupancy sensor (IPOS), which combines an inexpensive camera and computer vision algorithms that can recognize the presence of human occupants.
The MEMS Pulsed Emitter (MPE), a broadband source of quasi-black body pulsed light that operates over the 1-20 micron infrared (IR) spectrum, is designed with patented, thin-membrane, thermo-resistive material.
Designed to meet the challenging accuracy and reliability requirements of demand controlled ventilation systems (DCVs), the IRCO2 is a CO2 sensor for HVAC applications.
It’s no secret sensors play a critical role in building automation operation and efficiency. Their impact and effectiveness will depend on how the sensors correlate with other devices and components across the greater HVAC system. This requires some emphasis on effective design attributes and integration strategies.
Both the AquaGuard AG-1100E and AG-1175E are electronic condensate management sensors for metal secondary drain pans. They mount directly to the side of a metal secondary pan in seconds with a single thumbscrew, making any installation — commercial or residential — quick and easy.
Model SS610E has been added to the line of patented Safe-T-Switch® electronic condensate overflow control switches. It is designed for use on mini-split systems. It includes reliable, low power-consuming, state-of-the-art microelectronics.
Commercial controls prove their worth with all the data and other information they provide on the building and the work they perform day to day. Three products have been selected to receive awards in The NEWS’ ninth annual Dealer Design awards in the Commercial Controls category.
The United States market for sensors and controls for building energy management systems (BEMs) is forecast to rise at a 17 percent compound annual growth rate (CAGR) to $2.14 billion in 2020, while its European counterpart is forecast to reach $1.93 billion in 2020, a 19 percent CAGR.
