LDR 7mm

7mm LDR Photoresistor

7mm LDR Photoresistor is a light-dependent resistor used to sense changes in ambient light. Its resistance changes with illumination, so it is commonly used in voltage-divider circuits for automatic lighting and sensor lessons.

Moreover, this component is useful for makers, students and technicians who need a small, specific part rather than a generic replacement. Before installation, compare the name, value, pin count, package size and rating shown on the product with your circuit requirements.

7mm LDR Photoresistor Features

• Also, light-dependent resistor for detecting ambient light level.
• In addition, useful in automatic lighting, brightness sensing and learning circuits.
• For example, resistance changes according to received light, so it can be read by a divider circuit.
• Therefore, practical component for Arduino-style analog input experiments.

Specifications

• Size: 7mm

Applications

• However, automatic light control projects.
• Day/night detection and brightness sensing.
• Analog input experiments with microcontrollers.
• Educational sensor circuits.

Usage Notes

Use this part within the limits of your circuit design. For LEDs, switches, sound components and variable resistors, always check polarity, pinout, current path and mechanical fit before soldering or final assembly. If the product controls mains or high current loads, installation should be done by a qualified person and only within the printed rating.

Handling & Safety

Always confirm the rating, polarity and pinout of a ldr light sensor before installing it, and avoid exceeding its rated voltage or current. Use proper ESD precautions with sensitive parts. These steps protect your circuit and keep your work safe.

Why Choose This LDR Light Sensor

First, it is a widely used part in electronics repair, prototyping and assembly, so it fits into most existing projects easily. Second, the value, rating or pin count is clearly stated, so you can match it to your circuit with confidence. Third, our team checks basic function before it ships. So, you avoid guesswork when you order. As a result, this is a dependable choice for repair, prototyping or a finished project.

Usage Tips

Before soldering or installing, match the value, package and pin layout with your circuit diagram. Therefore, you avoid a wrong fit or a damaged board. Also, keep small parts stored in labeled bags so values do not get mixed up during a project. As a result, your build stays organized and easier to troubleshoot.

Good to Know

A well-matched ldr light sensor saves time on the job later. Therefore, double-check the value, rating and pin layout against your circuit before relying on it in a final build. Also, keep the original packaging until you have tested the part, since this makes any exchange easier if something is not right. As a result, your project stays reliable with fewer surprises.

شرح المنتج بالعربي

مقاومة ضوئية 7 مم يتغير خرجها حسب شدة الإضاءة وتستخدم في دوائر استشعار الضوء.

هذا المنتج مناسب لأعمال التجارب، الصيانة الخفيفة، التعليم، وتجميع الدوائر الإلكترونية عندما تحتاج إلى جزء محدد بقيمة أو مقاس واضح. قبل التركيب يجب مطابقة المواصفات الظاهرة في اسم المنتج مع الدائرة، خصوصًا الجهد، التيار، المقاومة، عدد الأطراف، ونوع التوصيل.

المميزات والاستخدامات

• يتغير حسب شدة الإضاءة المحيطة.
• مناسب لدوائر تشغيل الإضاءة تلقائيًا واستشعار الضوء.
• يستخدم عادة مع مقاومة أخرى لقراءة تغير الجهد.

لأفضل نتيجة، افحص مكان التركيب جيدًا قبل اللحام، واستخدم أدوات قياس مناسبة عند اختبار الدائرة. لا تعتمد على الشكل فقط عند اختيار القطعة؛ القيمة الكهربائية وطريقة التوصيل أهم من التشابه الخارجي.
