IR Emitter (Transmitter):

• Emitter Type: The IR emitter is a high-efficiency Infrared LED (light-emitting diode) designed to emit near-infrared light.
• Wavelength: Operating at a typical wavelength of around 850nm, the emitter provides a reliable source of invisible IR light.
• Voltage Requirement: The emitter requires a supply voltage of approximately 1.2V to 1.5V to emit IR light.
• Current Rating: It typically has a forward current rating in the range of 20mA to 100mA, ensuring efficient IR light emission.
• Radiation Pattern: The emitter generates infrared light in a specific radiation pattern, whether it’s a narrow beam or wide-angle, depending on the model.

IR Detector (Receiver):

• Detector Type: The IR detector is an IR-sensitive photodiode or phototransistor designed to sense the presence or absence of reflected or incident IR light.
• Wavelength Sensitivity: The detector is sensitive to infrared light at the same wavelength as the emitter, allowing it to efficiently capture reflected IR signals.
• Response Time: The photodiode or phototransistor offers a quick response to changes in incident light, making it suitable for detecting rapid changes in object presence.
• Output Signal: The detector produces a digital signal (high or low) based on the presence or absence of reflected IR light.

Operating Voltage: The module commonly operates at low voltage levels, typically around 3.3V or 5V, which ensures compatibility with various microcontroller and digital circuits.

Distance Sensing: This module is employed for detecting the presence or proximity of objects within a certain range, typically up to a few centimeters. The specific range may vary based on the application and module design.

Applications: SEN-00241 IR Emitter and Detector Modules are widely utilized in proximity sensing, object detection, and obstacle avoidance in robotics and interactive devices. They are also suitable for applications that require precise object detection.

Mounting: The emitter and detector components are conveniently integrated into a single module, which can be easily mounted on printed circuit boards (PCBs) or within enclosures.

Connection: The module provides separate pins for the emitter and detector, allowing straightforward interfacing with microcontrollers and digital circuits.
