pke Light Laser Switch – LDR Circuit Complete Project Circuit with 2 LED Built-in Board || Best School Projects from PKEnterprises:
An LDR is a component that has a (variable) resistance that changes with the intensity of light falling on it. This allows them to be used in light sensing circuits. Now security has become the primary concern of various buildings, homes and offices. For this purpose, there are a variety of security alarms available in the market that use different types of technology to detect the intruder such as infrared sensors, motion sensors, ultrasonic sensors, laser sensors, etc. This is a laser alarm safety sensor,
In this circuit, two LEDs come on the board, this means that when the LDR sensor senses this, the two LEDs turn on automatically, and when the LDR sensor senses the light, the two LEDs turn off automatically, perfect circuit for whoever wants to make an LDR or laser type circuit

2 variants available, without 9V battery and with 9V battery, choose as per your choice
Perfect integrated circuit for LDR laser light
2 LED lights turn on automatically in the dark and turn off automatically in the light, Easy to use and durable circuit, 100% tested, Made in India project
