4 Pin Photodiode Sensor Module

Input and Output

• Input: Light falling on the photodiode.
• Output: Provides an analog signal (voltage or current) that varies with the light intensity.

Physical Characteristics

• Dimensions: Compact module, typically around 20 mm x 20 mm.
• Material: Plastic or PCB with integrated photodiode chip.
• Weight: Lightweight, making it easy to integrate into small projects.

Technical Specifications

• Output Range: The output voltage or current is directly proportional to light intensity.
• Response Time: Fast response to changes in light, suitable for real-time measurements.

Additional Features

• Adjustable Sensitivity: Some models include components to adjust sensitivity for different light levels.
• Easy Integration: Designed for straightforward connection to microcontrollers or other electronic circuits.

How to Use

1. Connect the Sensor: Wire the VCC pin to your power supply (3.3V or 5V) and GND to ground. Connect the OUT pin to an analog input pin on your microcontroller or measurement circuit. The SIGNAL pin provides the light intensity output.
2. Power On: Supply power to the module.
3. Measure Light: The photodiode will convert the detected light into a corresponding analog signal.
4. Read Output: Use the analog input on your microcontroller to read the voltage or current from the OUT or SIGNAL pin. Higher values indicate more light intensity.
5. Adjust Sensitivity: If the module includes adjustment options, use them to fine-tune the sensor’s response to light.

The 4 Pin Photodiode Sensor Module is ideal for precise light measurement applications, providing reliable and accurate light detection for various projects.
