Motion Detector Circuit

Abstract

Nowadays, there are many types of house controlled system which is too expensive and difficult to use. For that reason, an effective house controlled system at low cost is built where user can also program the system by their own. Sensor is considered from the major component in this circuit so should be known the definition, types and applications of each type. Also microcontroller, switches, fans, LEDs and LCD were used for different purposes to fulfill circuit operation. So we found the passive infrared sensor and temperature sensor are an input components. While indicators LEDs, ventilation system, and LCD display are the output components, where it’s all controlled by controller circuit, we used all this components to design our model.
