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

INFRARED DETECTORInfrared light was first discovered back in 1801 by W.Herschel. Infrared is a form of radiated energy inwhich the wavelength

This causes a change in current from the drain tosource. Very little power is required at the gate tocontrol the larger current flow
