GL5516 LDR Light-sensitive resistor (photoresistor)

High-quality GL5516 5mm LDR (Light Dependent Resistor).

An LDR (Light Dependent Resistor) is a light-sensitive resistor that changes its resistance value depending on the amount of light falling on the LDR. The more light that falls on the LDR, the lower the resistance of the LDR will be. On the other hand, the less light that falls on the LDR, the higher the resistance of the LDR will be.

Very easy to use in combination with an Arduino, ESP8266, ESP32 or Raspberry Pi Pico
