This device adopts ordinary flashlight as remote command,and makes a controlled electrical socket.It can control the power state of electrical socket by pressing the flashlight switch within a few meters,so it is easy to use.IC can be replaced by AN7812,LM7812,W7812 and other models.The current amplification factor β of VT1~VT3 is about 200. RL1 and RL2 use MG44-03 plastic resin encapsulated photosensitive resistors,as well as other ordinary photosensitive resistors whose light photosensitive resistance≤ 5kΩ, dark photosensitive resistance ≥ 1MΩ resistor instead of the . T is the 8W~10W power transformer.
