Classrooms

What are the best occupancy sensors for classrooms?

Best Practices: Classrooms can vary widely in their use from an elementary setting for 25 to 30 students to larger lecture settings like that in a university. Always look closely at the typical actvities that will take place to layout sensors properly for best coverage of minor and major motion activities.

Small to Medium Sized Classrooms (20X20 to 40X40 and everything in between)

Typical Room Features: In classrooms of this size, a typical layout includes many hard surfaces such as desks, tables, file cabinets, chairs, hard surface flooring, chalk boards, white boards and hard surface walls. This makes an ideal environment for Ultrasonic technology. These hard surfaces often result in increased sensitivity and improved reliability for Ultrasonic sensors. When combining this technology with passive infrared sensors utilizing Multi-Technology sensors, you have a perfect scenario for flawless operation.

Classrooms that have ample ambient ligh from large amounts of windows can often take advantage of additional savings through the use of bi-level switching. Bi-Level switching allows the application of Dual Relay sensors or power packs which can switch inboard or outboard lamps in a fixture independantly. Utilizing the built in photocells of the sensors only the required amount of lamps need to be switched on during occupancy based on current light levels.

Best Sensing Technology: Multi-Technology and Ultrasonic Technology. Smaller classrooms (20X20) can use Passive Infrared Technology effectively.
