Photo Resistor Sensor LDR 10mm

From the shop's description

Photo Resistor Sensor LDR 10mm is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. These small 10mm LDR (Light Dependent Resistor) are also called a photoresistor. An LDR is a resistor whose resistance changes with the amount of light striking it. Key Features of Light Depentent Resistor: As the strength of the light falling on the LDR increases, the resistance of the LDR gets lower. It is typical to put the LDR in series with a resistor to create a voltage divider and feed that output to an analog input on an MCU. The output will be a lower voltage when no light is striking the sensor and the voltage will increase as the light intensity increases. These can be used in a variety of applications such as monitoring a pilot light, night light control or anywhere that you want to detect a basic threshold of light and take some action.
