As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

Also, while the green one of the LEDs is on, the RGB LED is also flashing green. when the system is activated, the red led lights up and the buzzer starts to play the note "Si". Meanwhile, the RGB LED ...

This Water Sensor is designed to detect water or liquid leakage. Convenient I2C interface makes it easy to add water leakage detection to any IoT application in seconds. Integrated on-board Buzzer can ...

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.

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.

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.
