There are many types of contactless sensors available in the market, including capacitive sensors, ultrasonic sensors, radar sensors and optical sensors. In this article, we are going to look at a ...

The amount of light reaching the LDR from the LED decreases as the pipe is bent, and with a simple divider circuit a voltage can be read by an Arduino.

Key instruments include LDR sensors, Arduino Uno, relay modules, and a power supply system. This project offers a practical solution to improve energy efficiency in offices, suggesting future ...

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...
