14+ Dark Sensor Circuit Diagram

14+ Dark Sensor Circuit Diagram. R1 = 330ω resistor r2 = 1kω resistor r3 = 1k variable resistor q1, q2 = bc547 transistor one photo resistor (ldr) one 6v dc power supply or battery. The circuit comprises elements like battery, diode, resisters, etc.

HOW TO MAKE A DARK SENSOR USING LDR and 555 TIMER from i0.wp.com

This may be useful in certain practical applications. Automatic dark detection circuit with alarm, dark detection circuit diagram and list of components of this project is given in this article. This ldr dark sensor using ldr circuit diagram used no any ic.ldr is used as dark and light sensor.

The circuit comprises elements like battery, diode, resisters, etc.

14+ Dark Sensor Circuit Diagram. For this, we need a light sensor to detect the light condition and some circuitry to control the light sensor. Basically a darkness sensor circuit turn on a light in darkness and turn off light in brightness. This is part of an automatic animal feeder. The dark sensor circuit described here stops the musical sound when darkness is detected like when you put your hand above the sensor.
