Specification

Overview

Specifications: The QRE1113 reflective optical sensor is designed for detecting changes in reflective surfaces. It consists of an infrared LED emitter and a phototransistor receiver in a compact package, capable of detecting variations in light intensity based on the distance and reflectivity of objects.

Power: Typically operates on a voltage supply ranging from 4.5V to 5.5V DC, with a low current consumption suitable for battery-powered applications.

Input and Output: Provides a digital output signal that changes state based on the presence or absence of reflected infrared light. It interfaces with microcontrollers or digital circuits via a simple wiring connection.

Physical Characteristics: Compact and lightweight, the QRE1113 sensor is housed in a small plastic casing with integrated emitter and receiver components. It features mounting holes or adhesive backing for easy installation on robotic platforms, line-following robots, or interactive displays.

Additional Features: Includes ambient light rejection to minimize interference from external light sources, ensuring accurate detection in various lighting conditions. Offers adjustable sensitivity and detection range for adapting to different reflective surfaces and distances.

This sensor is widely used in DIY electronics projects, robotics, and automation systems where precise object detection or line following is required. Its simplicity, affordability, and reliable performance make it popular among hobbyists and engineers for integrating into interactive devices and sensor-based applications.
