Circuit Diagram Light Sensor. White wire is the neutral wire which is typically shared or connected with the light fixture and the sensor or detector. It detects the quantity of light present in the environment and the results can be detected by the brightness of the led.
Circuit design of light sensor as the photo resistor or ldr is a variable resistor a voltage divider network must be used to gets the analog equivalent output from it. The light sensor circuit is an electronic circuit designed using light sensor ldr darlington pair relay diode and resistors which are connected as shown in the light sensor circuit diagram.

Light detector sensor circuit diagram.
The circuit of light detector is very simple and easy to build with very few components. The automatic light sensor circuit can be used for controlling the electrical appliances such as light fan cooler air conditioner street light etc automatically. This is a simple light sensor circuit diagram which activates a relay when light incident on sensor is above thresholdthis circuit cost less.
