Dark/Light Activated Circuit using LDR The dark sensor circuit is very useful to Automatic Switch ON and OFF any appliance by Detection of Light and Dark. LDR is a photoresistor that is used for the detection of light. When Light intensity high on LDR, The Resistance through it Decrease and When Light intensity is Low …
Light/Dark Activated Switch circuit without Relay The Working Principle of this Automatic Bulb Switch same as My previous Project Automatic Transformerless Light Switch.  But Here Used A Triac At the place of Relay. In the circuit, There is no used Relay for switching. This is Automatic Light Controlled Bulb Switch With LDR Using Without Relay When …
LDR circuit diagram LDR darkness sensor circuit This is an Automatic Night Light circuit Without Transformer operated by Light Using Light Sensor LDR (Light-dependent resistor). This Transformerless Automatic Light operated Night Light circuit is very simple and easy. At DayThe Bulb is an automatic switch off and At night Automatic Switch ON Automatic Night Bulb …
LDR circuit diagram Dark sensor circuit This is a light-controlled LED light Dark sensor circuit, Light-activated switch, which fully depends on Light. LDR is used in this for sensing the DARKÂ and LIGHT. LDR is a Light Dependent Resistor which resistance increases as darkness and its resistance is Decreases when Light falling on it. automatic …
Automatic ON OFF light switch circuit This is a light operated Relay circuit . Light Dependent Resistor(LDR ) is used to operate the switching Function of this circuit. This circuit is used to Switched on light At night Automatic and switch OFF in DAY light (sunlight) Automatic . There is no need to switch on …
