Key Features:
- Light Intensity Detection: Converts ambient light levels into an analog signal
- Wide Voltage Compatibility: Operates on 3.3V – 5V, perfect for Arduino, ESP32, and Raspberry Pi
- Simple Interface: Outputs analog signal (AO) for varying light intensity
- High Sensitivity: Detects changes in ambient light for automatic brightness control and light-based automation
- Compact Design: Easy to integrate into DIY electronics projects
Technical Specifications:
- Module Type: KY-018 Photoresistor Module
- Operating Voltage: 3.3V – 5V
- Output: Analog voltage based on light intensity
- Sensor Type: Photoresistor (LDR – Light Dependent Resistor)
- Size: Compact for embedded applications
How It Works:
- The photoresistor (LDR) changes resistance based on light intensity.
- More light = lower resistance, resulting in a higher analog output.
- Less light = higher resistance, resulting in a lower analog output.
