Description
TeknoCrafters FA3041 Photosensitive Resistor Sensor Module (KY-018 Class)
The TeknoCrafters FA3041 is a compact and efficient photosensitive resistor sensor module, modeled after the KY-018 platform. It integrates a light-dependent resistor (LDR) and a 10kΩ fixed resistor to form a voltage divider circuit, providing an analog voltage output that varies with light intensity. This module is ideal for applications requiring ambient light detection and is compatible with microcontrollers such as Arduino, ESP32, and ESP8266. For Raspberry Pi users, an external analog-to-digital converter (ADC) is necessary due to the lack of native analog input.
