The Arduino Nano LDR (Light Dependent Resistor) or photoresistor module detects changes in light intensity, providing analog output based on ambient light levels. It's used in projects requiring light ...

LiFi (Light Fidelity) is a wireless communication technology that uses visible light communication (VLC) to transmit data. VLC is a type of optical wireless communication (OWC) that uses light as the ...

Light sensors are widely used in electronic applications. The most common one used is a photoresistor or light-dependent resistor. Despite a long response time, this sensor is inexpensive and useful ...

This IoT-based project monitors soil moisture, temperature, and humidity levels near plants and light intensity near the control station. It turns on water solenoid valve when moisture level goes ...
