Project – Photodiode – 5mm IR Receiver LED

An IR photodiode can be used to detect IR light. It is commonly used in security camera, it can also be found in IR proximity sensor or line follower sensor in combination with IR transmitter. The diode allows some current to flow through it which is proportional to the amount of IR light falling on it.

5mm Photodiode Features:

• Fast response time
• High Photo Sensitivity
• Small Junction Capacitance

Applications:

• Used to detect Light and its intensity
• Used with IR LED for object detection, counting, encoder and more
• Used in automatic door sensors
• Used in line follower and object avoiding robot
• Distinguish between Day and night
• Automatic light (streetlight or vehicle light)  control
