The **IRS080-R55VF22** is a high-performance infrared (IR) sensor module, typically utilized in industrial automation, security systems, and proximity sensing. This part belongs to a class of sensors designed for reliable object detection through the emission and reception of infrared light. --- ### 1. Key Technical Specifications The following table outlines the primary electronic characteristics of the IRS080-R55VF22: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Sensing Range** | 80mm - 550mm | Variable detection distance based on calibration | | **Output Type** | Analog/Digital Pulse | Varies by specific sub-model configuration | | **Supply Voltage** | 4.5V - 5.5V DC | Standard low-voltage operation | | **Current Consumption** | ~30mA | Typical power draw during active sensing | | **Light Source** | Infrared LED | Peak wavelength usually around 850nm - 940nm | | **Response Time** | < 20ms | High-speed detection for moving objects | --- ### 2. Core Electronic Components The internal architecture of the module consists of several critical stages: 1. **Emitter (IR LED):** Pulses infrared light at a specific frequency to avoid interference from ambient light sources (like sunlight or indoor lamps). 2. **Receiver (Photodiode/Phototransistor):** A high-sensitivity component with an optical filter that only allows the specific IR wavelength to pass through. 3. **Signal Processing Circuit (ASIC):** An Integrated Circuit that amplifies the weak signal from the receiver and filters out electrical noise. 4. **Voltage Regulator:** Ensures that fluctuations in the input power supply do not affect the accuracy of the distance measurement. --- ### 3. Connection Pinout A typical integration for this sensor follows a standard 3-pin or 4-pin configuration: ```c++ // Example Pseudocode for reading sensor data int sensorPin = A0; // Analog input pin int sensorValue = 0; void setup() { Serial.begin(9600); } void loop() { sensorValue = analogRead(sensorPin); // Read the infrared intensity Serial.println(sensorValue); delay(100); } ``` --- ### 4. Applications * **Touchless Switches:** Used in sanitary equipment (automatic faucets, soap dispensers). * **Proximity Sensing:** Detecting the presence of an object in assembly lines. * **Security:** Perimeter monitoring and entrance detection. * **Robotics:** Obstacle avoidance and wall-following logic.
