Infrared Sensor for Wireless Microphone System

IR Pulses that are invisible light pulses. Ideally, the IR Sensors should be line-of-sight‮ to the microphones. The microphones output very strong IR pulses that will reflect off wall, ceiling and hard floor surfaces and are then ‘seen‮ by the sensors which enhances system performance when a microphone is moving around a class room. The IR Sensors should be installed on wall surfaces as high up the wall as possible (in a normal ceiling room) and one should be installed on each side of the room for best coverage.

• 2.06MHz or 2.56MHz carrier frequency
• IR pulses that are invisible light pulses
• IR sensors should be line-of-sight to the microphones
• Suitable for wireless microphone system
