This is because of the increasing amount of lights in a home or society which creates huge consumption of electricity and currently that is one of the major issue the society is worried about. Sensor based light system are not real-time because the sensor gets activated due to various environmental changes. To overcome this problem, many researchers are developing cost-effective custom-based Smart Light systems, which are affordable for everyone. Most of those systems use a Passive Infrared (PIR) motion sensor for motion detection. Although affordable, such a system still has many limitations. For example, false light triggered due to an abnormal condition such as rapid heating from aging of the devices, animals or insects passing/blocking the sensor, etc.enVision ProcessingMicrocontrollerVision Based Smart Light System Using OpenCV on Nodemcutext::report
