Week 8 : Methodology Part 2 - Motion Detector

In this project, a motion detector circuit, will be used to detect the presence of the vehicle on the road. If there is a vehicle moving pass the motion detector circuit, it will trip the circuit and lamp will be switch on. The  advantage of this circuit, it will prolong the lifespan of battery and lamp bulb. Imagine there is no vehicle using the road, electricity will be drawn from the battery to power up the lamp throughout the night. Although the electricity is free, which we get from sunlight, but we need to consider the battery and lamp bulb as well.

Picture above is a schematic diagram for infra-red motion detector circuit.
