These sensors output binary signals used to control an LED light and a fan via a Logic Array using AND and NOT gates. The system operates as follows: Light Sensor (L): • Outputs 0 if it is dark. • ...

This ATmega32 AVR Microcontroller based project covers an automatic staircase light circuit using PIR sensor and LDR. It check two conditions to start the lights: presence of darkness and motion ...

The project is an automatic switch for 2 LED lamps used to illuminate some plants in my house. On board there is a real time clock, to keep track of the actual date and time even on power loss, and ...

Abstract: In this paper we utilize a light sensor device with a fuzzy logic controller (FLC) to sense the brightness of different environments and to automatically adjust backlight brightness to a ...
