PIR motion detector, General purpose motion detector
This motion detector circuit uses a low cost LM324 quad operational amplifier as both a two stage amplifier and a window comparator. Amplifiers IC1A and IC1B have a gain of 100 each for a total of about 10,000. IC1C and IC1D form a window comparator that responds to signals about 200 millivolts above and 200 millivolts below Vcc/2. This window is set by the low current voltage drops across D1 and D2. Comparator outputs feed through D3 and D4 that pass only the positive transitions into CD4538 CMOS single shot IC2 which feeds into Q1 that drives relay RY1.
Direction sensing motion detector This motion detector circuit will both detect motion and indicate the direction that an infrared emitting body is moving. The amplifier and comparator circuits This type of motion detector can be used to indicate people entering or leaving a building or in some robotic applications.
