A sensor is a device that detects and responds to physical world input.It is a module, machine, or subsystem that detects events or changes in its surroundings and conveys the data to other ...

This Arduino project is used for gas leakage detection by a gas sensor which senses the hydrogen concentration in the air. This sensor can detect hydrogen gas concentrations anywhere from 100 -10000 ...

In this tutorial, we will use one such sensor BH1750 Light Sensor Module and interface it with Arduino and show the Lux value over 16x2 LCD.

In this project we are making a Light Sensor using LDR with Arduino to control a light bulb/CFL as per light condition of the room or outside area.

Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to ...

LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and gas sensors ...

The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is used to ...

At one end is an LED and at the other the LDR, and when attached to a glove it provides a finger sensor without the fuss.
