Photodiode Light Sensor Experiment

Overview

This experiment uses a photodiode to detect light and convert it into an electrical signal. The voltage output from the photodiode changes depending on the intensity of the light hitting it.

Components Required

• Photodiode
• Resistor (10kΩ)
• Power Supply (5V)
• Multimeter

Procedure

Follow these steps to set up the experiment:

1. Connect the photodiode in reverse bias configuration.
2. Attach a resistor in series with the photodiode to limit the current.
3. Measure the output voltage with a multimeter as the light intensity changes.

Expected Result

The voltage output will vary depending on the light intensity hitting the photodiode. A stronger light intensity will result in a higher voltage, and a weaker light will result in a lower voltage.
