The **IRS080-R55OF03** is a high-performance infrared (IR) sensor module, typically utilized in gesture recognition, proximity sensing, and object detection systems. It is part of a specialized series of optical sensors designed for industrial and consumer electronics automation. --- ### 1. Component Overview This part is an integrated optical system that combines an infrared emitter and a receiver into a single compact housing. | Feature | Specification Details | | :--- | :--- | | **Part Number** | IRS080-R55OF03 | | **Sensor Type** | Infrared (IR) Proximity / Gesture Sensor | | **Interface** | Typically I2C or Analog (depending on driver IC integration) | | **Detection Range** | Optimized for 0mm to 80mm (suggested by "080" prefix) | | **Packaging** | SMD (Surface Mount Device) with optical window | --- ### 2. Key Electronic Characteristics The module operates based on the principle of **Infrared Reflection**. Here are the primary electronic functional blocks: 1. **IR LED Emitter:** Pulses infrared light (usually around 850nm - 940nm) towards an object. 2. **Photodiode Array:** Captures the reflected light. The "R55" designation often refers to specific sensitivity curves or field-of-view (FOV) parameters. 3. **Signal Processing ASIC:** Normalizes the signal, filters out ambient light noise (to prevent false triggering from sunlight or indoor lamps), and converts the raw light data into a readable output. 4. **Optical Filters:** The "OF" in the part number often indicates an integrated **Optical Filter**, which narrows the spectral response to only detect the specific wavelength of the emitter. --- ### 3. Pin Configuration & Application While specific pinouts can vary by manufacturer (often associated with brands like Everlight or specialized Shenzhen-based opto-electronics firms), the standard layout includes: * **VCC:** Power supply (typically 2.5V to 3.6V). * **GND:** Ground. * **LED Control:** Controls the pulse frequency of the IR emitter. * **Output (OUT/SDA-SCL):** Digital data stream or analog voltage representing distance/reflection intensity. ### 4. Common Applications * **Sanitary Automation:** Automatic faucets, soap dispensers, and hand dryers. * **Mobile Devices:** Screen dimming/off during phone calls (proximity sensing). * **Industrial:** Paper detection in printers or object counting on assembly lines. * **Consumer Electronics:** Touchless light switches or lid-opening mechanisms. ---
