The function of the photoresistor tracking module
The KY-018 Photoresistor module is used to measure light intensity. It can be used for various purposes, such as adjusting the brightness of a device, detecting day and night, or activating a light switch. Compatible with many popular microcontrollers like Arduino, ESP32 and others. The module supports analog output and digital output, equipped with a power indicator light, a signal indicator light, and a potentiometer for adjusting the light the digital output. The module typically consists of a photoresistor (also known as an LDR or Light Dependent Resistor) and additional circuitry to make it easier to interface with. The Photoresistor module is a light sensor based on a photoresist, also known as a light-dependent resistor (LDR) or photocell, which is a type of resistor that changes its resistance in response to the intensity of light falling on it.
