The **IRS100-R11MF33** is a specialized electronic component typically used in sensing, detection, and motion tracking applications. It falls under the category of **Infrared (IR) Sensors**, often integrated into modules for industrial automation, robotics, or proximity detection. ### 1. Technical Specifications The part number indicates a specific configuration of an infrared receiver or sensor module. Below are the typical technical parameters associated with this series: | Parameter | Description | Typical Value/Type | | :--- | :--- | :--- | | **Component Type** | Infrared Receiver Module | Photo-diode/IC Hybrid | | **Wavelength** | Peak sensitivity | ~940nm (Near-Infrared) | | **Operating Voltage** | VCC range | 3.3V to 5.0V DC | | **Detection Range** | Distance capability | 10cm - 100cm (Adjustable) | | **Output Type** | Signal logic | Digital (High/Low) or Analog | | **Carrier Frequency** | For noise immunity | 38 kHz (Standard) | --- ### 2. Key Electronic Features * **Integrated Circuitry:** Unlike a simple photodiode, the "IRS" series usually includes a pre-amplifier, a limiter, a bandpass filter, and a demodulator inside the package. * **Ambient Light Rejection:** It is designed to ignore sunlight and artificial room lighting, focusing only on the specific IR frequency. * **Low Power Consumption:** Optimized for battery-powered devices or low-current industrial loops. * **Compact Form Factor:** The "MF33" suffix usually refers to a specific lead-frame shape or surface-mount (SMD) package style. --- ### 3. Pinout Configuration While pinouts can vary slightly by manufacturer, the standard 3-pin configuration for this series is: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **Vout** | Output signal to Microcontroller (MCU) | | 2 | **GND** | Ground / 0V | | 3 | **VCC** | Power Supply (3.3V/5V) | --- ### 4. Application Logic The IRS100-R11MF33 is frequently used in a **reflective** or **interrupted** circuit. ```cpp // Example: Arduino Logic for IR Detection int irSensorPin = 2; // Connected to Vout void setup() { pinMode(irSensorPin, INPUT); Serial.begin(9600); } void loop() { int detection = digitalRead(irSensorPin); if (detection == LOW) { Serial.println("Object Detected!"); } delay(100); } ``` --- ### 5. Common Use Cases 1. **Industrial Counting:** Detecting items on a conveyor belt. 2. **Safety Barriers:** Triggering a stop if a hand or object breaks the beam. 3. **Consumer Electronics:** Proximity sensing in smart faucets or automatic soap dispensers. 4. **Robotics:** Obstacle avoidance and line following.
