An LDR Sensor (Light Dependent Resistor Sensor) automatically controls outdoor lighting by switching lights ON at dusk and OFF at dawn based on ambient light levels. Unlike motion sensors, it responds to changes in natural light, making it ideal for street lights, garden lighting, parking areas, boundary walls, and commercial outdoor applications. Esysense LDR Photocell Sensors are available in 6A, 10A, 16A, and 20A variants with IP65-rated weatherproof protection and adjustable light sensitivity. They provide reliable day/night automation, improve security, reduce manual switching, extend lamp life, and help lower unnecessary electricity consumption in residential, commercial, and industrial environments.
