The circuit design follows a modular approach, with separate modules for the infrared sensor, voltage regulation, clock generation, countdown timer, and power switching. The modules are interconnected ...

Door sensor for automatic lighting control is widely being developed for energy saving and security purposes. An infrared door sensor based on electrical and electronics combinational circuit ...

Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world’s first all-integrated sensor circuit based on ...

Abstract: In this paper we propose a design using both a microprocessor and light sensors for automatic room light detection and control. Our design, the HLCM (Home Light Control Module) which will be ...

Project Overview This project automates street light operation based on ambient light levels using an LDR (Light Dependent Resistor) and a microcontroller (Arduino). At night, the resistance of the ...

In the circuit, the voltage at pin 3 is set by VR1 so as to keep the output high in a particular light level. The high output keeps the LED off. The PN Photodiode act as the light sensor. When the ...
