KY-018 Photoresistor Module
Overview:
The KY-018 Photoresistor Module is a light-dependent sensor designed to detect ambient light levels. It consists of a light-dependent resistor (LDR) and a 10kΩ fixed resistor, forming a voltage divider circuit. As light intensity increases, the resistance of the LDR decreases, making this module ideal for light-sensing applications. It outputs an analog signal corresponding to the light intensity, which can be easily read by microcontrollers like Arduino and Raspberry Pi.
