IR Infrared Transmitter Diode

Wiring Connections:

• Anode (Positive Pin): Connect to the positive voltage supply through a current-limiting resistor.
• Cathode (Negative Pin): Connect to the ground or negative terminal of the power supply.

To connect the IR transmitter diode:

• Step 1: Identify the anode and cathode pins of the diode. The anode is usually the longer pin or the one connected to the positive side.
• Step 2: Connect the anode pin to the positive terminal of your power source ( through a current-limiting resistor to prevent damage).
• Step 3: Connect the cathode pin to the ground or negative terminal of your power source.
• Step 4: Ensure the connections are secure and the diode is correctly oriented.

Power:

• Voltage Requirement: Operates  between 1.2V to 1.5V DC.
• Current Consumption: Standard operating current is 20 mA. Exceeding this current may damage the diode.
• Power Supply: Use a regulated power source to ensure stable operation and prevent damage.

Input and Output:

• Input: The input to the IR transmitter diode is the electrical power supplied through the anode and cathode pins.
• Output: The output is infrared light emitted from the diode. This light is not visible to the human eye but can be detected by IR sensors or receivers.

Physical Characteristics:

• Size: Compact and small,  around 3 mm to 5 mm in diameter.
• Housing Material: Usually encapsulated in a clear or black plastic housing to protect the internal components.
• Mounting: Can be mounted on a PCB (Printed Circuit Board) or embedded in custom housings for various applications.

Technical Specifications:

• Wavelength: Emits infrared light at a wavelength of approximately 940 nm.
• Forward Voltage:  1.2V to 1.5V DC.
• Forward Current: Standard operating current is around 20 mA.
• Beam Angle: The emission angle is usually between 20 and 30 degrees, providing a wide coverage area.
• Response Time: Fast response time suitable for real-time communication and sensing applications.

Additional Features:

• Non-Visible Light: Operates using infrared light, making it useful for applications where visible light might interfere or be undesirable.
• Wide Application Range: Suitable for remote controls, object detection, and various communication systems.
• Durability: Built to withstand continuous use and has a long operational lifespan.

How to Use:

• Step 1: Identify the anode and cathode pins of the IR transmitter diode.
• Step 2: Connect the anode pin to the positive terminal of a power supply through a current-limiting resistor.
• Step 3: Connect the cathode pin to the ground or negative terminal of the power supply.
• Step 4: Ensure the power supply voltage is within the operating range of 1.2V to 1.5V.
• Step 5: Use the diode in conjunction with an IR receiver or sensor to detect the emitted infrared light. The receiver will pick up the IR light and convert it into an electrical signal.
• Step 6: Integrate the IR transmitter diode into your project, such as remote controls, obstacle detection systems, or communication devices.
• Step 7: Test the setup to ensure the diode is emitting IR light as intended. Use an IR receiver or sensor to verify proper operation and adjust the positioning as needed.
