Abstract
A method of sensing motion in a predetermined area is provided. The method may include using a digital output motion sensor to produce a digital output signal indicative of the presence of motion in the predetermined area. The method may further include transmitting the digital output signal along a signal path independent of analog amplification and filtering. The method may also include using a microprocessor coupled to the signal path to receive the digital output signal and to process the digital output signal.
