This project has a lot of potential and it can be applied to domestic and commercial use.ġ.3) In Human Dependent Lighting System, we used PIR Sensor which is used to receive the infrared rays that are emitted by human body and Light Dependent Resistor(LDR) to measure the intensity of ambient light. A light intensity control circuitry is made to turn ON the required number of lights based on surrounding light intensity, thereby reducing the wastage of electricity. The human dependent lighting system is a project based on PIR sensors to detect human presence. In order to overcome this issue, we developed a human dependent lighting system to use the electricity smartly which can save huge amount of electricity. This leads to unnecessary wastage of electricity. For instance, lights in various departments would remain switched ON even after working hours, when employees were not present in the office. The wastage of electricity is mainly due to carelessness of users. ![]() I was appointment as a group leader for this project by our tutor.ġ.2) In every department of an industry, there is a wastage of electricity resulting in high electric bills. This project was implemented as part of my academic curriculum “Project – 1” and it took us three months (July 2012 to September 2012) from inception, testing to implementation of the project. I started this project with a team of three engineers including myself under the guidance of our tutor and head of department, during the initial months of 7th semester, Bachelor of Engineering (Electronics and Communication). 1.1) A detailed description of the project “Human Dependent Lightning System” is presented in this career episode. ![]()
