Each single pair of sensors can monitor 1 cage with 16 IR beams or 2 smaller cages with 8 IR beams.
Software computes animal activity and animal position within the cage.
Each sensor functions as both emitter and receiver. Each sensor is equipped with its own microcomputer for scanning IR beams and communication with computer. Double modulation of IR beams and use of infrared filters provide high sensitivity and immunity to ambient light interference. Up to 64 sensor pairs can be used in a single Opto-Max Animal Activity System to monitor 64 animal cages with 16 IR beams each or 128 animal cages with 8 beams assigned to each animal cage. When positioned opposite another similar sensor, each pair produces 16 infrared light beams intersecting the animal cage.
