INTRODUCTIONThe AK-510 is an infrared motion detector kit. The objective of the kit is to teach the operations of the foursections that make up the ki

INFRARED DETECTORInfrared light was first discovered back in 1801 byW. Herschel. Infrared is a form of radiated energyin which the wavelength is longe

of the FET. This causes a change in current from the drain to source. Very little poweris required at the gate to control the larger current flow from

NEGATIVE FEEDBACKThe open loop gain (or maximum gain) of a typical op-amp is very high(usually greater than 100,000), enabling a very small input volt

BAND PASS FILTERThe combination of a low and high pass filter create what is called a BandPass Filter. The frequencies passed by each filter overlap a
