LDR Sensor Full Form In English
An LDR Sensor, also known as a Light Dependent Resistor, is a type of electronic component whose resistance changes according to the intensity of light falling on it. When light increases, its resistance decreases, and when light decreases, its resistance increases. This property makes LDR sensors useful in light-sensing devices like automatic street lights, solar garden lamps, and alarm systems. LDR sensors are inexpensive and simple to use, which is why they are widely used in educational projects, IoT applications, and industrial automation systems.
LDR Sensor Full Form In Hindi
एलडीआर सेंसर, जिसे लाइट डिपेंडेंट रेज़िस्टर कहा जाता है, एक ऐसा इलेक्ट्रॉनिक उपकरण है जिसकी रेज़िस्टेंस (प्रतिरोध) उस पर पड़ने वाली रोशनी की तीव्रता के अनुसार बदलती है। जब रोशनी बढ़ती है तो इसकी रेज़िस्टेंस कम हो जाती है और जब रोशनी कम होती है तो रेज़िस्टेंस बढ़ जाती है। इस गुण के कारण एलडीआर सेंसर का उपयोग ऑटोमैटिक स्ट्रीट लाइट, सोलर लैम्प और अलार्म सिस्टम जैसे उपकरणों में किया जाता है। यह सस्ता और उपयोग में आसान सेंसर है जो विभिन्न प्रोजेक्ट्स और औद्योगिक प्रणालियों में व्यापक रूप से इस्तेमाल होता है।
