निम्नलिखित में से कौन सा LDR सेंसर एप्लिकेशन का उदाहरण है?
Which of the following is an example of an LDR sensor application?
-
Lights: LDRs are famously used in automatic street lighting and garden lights. The LDR detects when it gets dark and triggers a circuit to turn the lights on.
-
Clock: LDRs are commonly used in digital clocks and electronic displays for automatic brightness control. By sensing ambient light, the device can dim the display in a dark room or brighten it in a sunny environment.
-
Voltage Divider: This is a fundamental circuit configuration used to interface an LDR with a microcontroller. Because an LDR changes its resistance based on light, placing it in a voltage divider circuit allows the system to convert that change into a readable voltage signal (which the microcontroller can then process).
Correct Answer: D) All of above
