LDR Sensor Project Overview This project demonstrates a simple light-dependent resistor (LDR) sensor circuit built using basic electronic components such as an LDR, transistor, resistor, and a ...

Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

This project presents a light-responsive power-saving system designed using Arduino and basic electronic components. The system starts in an active state (system LED ON). When ambient light is low, ...

Abstract: In the past few years, the technologic evolution of communication and information systems had a major impact in our lives. In education, this evolution broke some geographical barriers, ...

Abstract: Nowadays, using photovoltaic (PV) cells is among the power generation methods that absorb solar energy and convert it into electrical energy. The sun moves from east to west during the day ...
