Detail Description

LDR Sensor 3mm, also known as a Light Dependent Resistor, is a passive electronic component that changes its resistance based on the amount of light falling on its surface. When exposed to bright light, its resistance decreases, and in darkness, its resistance increases significantly.

The 3mm LDR is compact in size, making it suitable for small electronic circuits and compact project designs. It is widely used in light-sensing applications such as automatic street lights, day–night switches, burglar alarms, and light-controlled automation systems. The sensor is easy to interface with Arduino, ESP32, ESP8266, and other microcontrollers using a simple voltage divider circuit.

Due to its simplicity, low cost, and reliable performance, the 3mm LDR sensor is ideal for students, hobbyists, and professionals working on electronics learning kits, IoT projects, and basic automation circuits.

🔹 Key Technical Information (Important)
