Description
Product Description
The Infrared (IR) Sensor Module is a compact sensor board designed for detecting nearby objects using infrared light. It can be used for obstacle detection, object sensing, line-following robots, counting applications, and automation projects.
The module uses an infrared transmitter and receiver to detect reflected IR light from objects. Its output can be connected to a microcontroller such as an Arduino for digital object detection and control applications.
An onboard adjustment control on common versions allows the detection sensitivity or switching threshold to be adjusted according to the application.

How It Works
The IR transmitter emits infrared light. When an object comes within the sensing area, some of the IR light is reflected back toward the receiver. The module detects this reflected signal and changes its output state.
The output can then be read by a microcontroller to perform an action such as stopping a robot, changing direction, activating a motor, or triggering an alarm.
Important Note
The exact operating voltage, detection distance, output logic, pin configuration, and sensitivity range can vary depending on the specific IR sensor module version. Detection performance is also affected by object color, surface, angle, ambient light, and distance.
This module is intended for general-purpose electronic sensing and is not a precision distance-measurement sensor.
| This is an Infrared based proximity sensor which are great for obstacle avoidance and line following robots. Our infrared transceiver module contains an infrared transmitter and a receiver fit in a compact form on a tiny board. Transmitter emits infrared light and another receiver (photo-transistor) receives that IR light after reflection. The module can be used to identify an obstacle or a nearest object
