DHRUV-PRO 2-Pc 220V as30 Auto Day/Night On & Off Photocell, LDR Sensor Switch(White)

About this product

Overview The product can turn on or turn off light by automatically according to ambient-light. Ambient-temperature and humidity can’t affect it. It is not only convenient but also practical; it can control the load working only at night. For instance road light, garden light etc. Specification est 1. Switch on the power. 2. Please using enclosed black opaque bag in the packing when you testing in daytime. 3. When the bag mantles the detection window of the photocell, the ambient light of the items will be dark, it makes lamp on. 4. When take off this bag, it makes lamp off by automatically. Caution 1. In front of the photocell, it should be no obstruction effecting to accept natural light; 2. In front of the photocell, it should be no swaying object. 3. Light sensor: clock-wise adjust will increase light sensor value(can work at the daytime), Anticlockwise will reduce light sensor value(can work at night). Proper Way Of Installation 1. We have to install it above the load or bulb so that it can be in contact with darkness as well as sunlight for proper functioning. 2. Having 3 Wire A) RED WIRE : LOAD WIRE B) BLUE WIRE : COMMON WIRE C) BROWN WIRE : PHASE WIRE Functions On The Product All the basic technical and setting details are written all the product 10amp Photocell Snesor Working A photocell sensor works by detecting the amount of ambient light in its environment and controlling an electrical load, such as lighting, based on the light levels. Here's how a photocell sensor works: Light Detection: The photocell contains a light-sensitive component, usually a cadmium sulfide (CdS) cell or photodiode, that measures the intensity of ambient light. This component decreases resistance when exposed to light and increases resistance in darkness. Automatic Switching: Based on the light levels, the photocell sends a signal to a relay or switch to either turn the connected load (such as a light) on or off. When the light levels drop below a preset threshold (like at dusk),
