LDR SENSOR 5mm - LIGHT DEPENDENT RESISTOR PHOTORESISTOR
This 5mm LDR changes resistance with the change in the ambient light exposure on the surface of the sensor. LDR (Light Dependent Resistor) is a type of photocell which finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or Indoor automatic light switch. The 5mm LDR (Light Dependent Resistor) is a compact and sensitive photoresistor used to detect ambient light levels in Arduino, automation systems, and light-based sensor circuits. Perfect for DIY electronics, STEM kits, and smart lighting.
