Light Sensitive Relay at Carlos Cristopher blog

Light Sensitive Relay. This light sensitive circuit can operate a relay to switch on lamps or any ac loads when it senses darkness. Light activated relay switch and alarm boards from our electronic kits & modules range for industrial, professional, educational and hobby applications. The diagram below shows the proper figure of the lm741 light sensor relay switches circuit project/schematic. Its resistance is low about 100 ohms in bright light but increases to 10 meg or more in dark. These switches are commonly used in outdoor lighting systems to control when lights should be turned on at dusk and turned off at dawn. Ldrs are sensitive, inexpensive, and readily available devices with power and voltage handling capabilities similar to those of conventional. Ldr is used as the light sensor. Just add 5v power and hook up the load you want to control then adjust the potentiometer to set the brightness level at which you want the relay to switch between on / off. It is ideal to use as switch less night lamps driver.
