Light activated switch circuit light activating and deactivating switches are simple to build when you are provided with a ldr sensing element and 555 switch activator.

Light activated switch schematic.

These kind of sensor circuits are widely employed in many applications and may come in handy when you intend to build a simple light sensing circuit. The light activated switch circuit mainly consists of two components. The comparator ic lm358 and the ldr. In today s post i m going to share a simple light activated relay circuit.

Automatic street light circuit diagram. The lm358 ic has 8 pins and can have supply voltages ranging from 3 32 volts. Light activated switch circuit mini project. The ldr must be placed outside the box meaning its sensing surface should be exposed toward the ambient area from where the light level is required to be sensed.

Ldr is a light dependent resistor which resistance increases as darkness and its resistance is decreases when light falling on it. The circuit can be used as an automatic street light controller system or a simple light activated switch. Which is the circuit diagram below. Light activated switch circuit.

While the assembly diagram in figure 2. This is the light operated automatic night bulb switch circuit diagramusing without relay in this a triac is used at place of relay and ldr for light sensor. You can say dark activated switch. This is a light controlled led light circuit light activated switch which fully depends on light.

Switches including those reacting to changes in lighting are still very popular and practically used by electronics or automation specialists. This is the circuit diagram of a light activated switch based on national semiconductors comparator ic lm 311 and a ldr. Ldr is used in this for sensing the dark and light. Schematic of automatic light activated switch circuit.

A simple light activated switch description. Automatic light operated switch circuit using ldr triac optocoupler without relay. This time we propose to make a simple light responsive switch system but powered directly from 230 v ac. The circuit is based on a voltage comparator circuit wired around ic 1 the non inverting in put of ic1 is given with a reference voltage of 6v using resistors r3 and r4.

This light activated relay circuit presented here uses the 555 timer ic and a light dependent resistor or ldr to form a light sensitive relay in an intruder alarm system or for switching on a lamp at sun set and off at sun rise.
