Description: A reflective sensor is a device that detects the presence of objects by measuring the light reflected from them. This type of sensor emits a beam of light, usually in the visible or infrared spectrum, and measures the amount of light that returns to the sensor after being reflected by a nearby object. The main feature of reflective sensors is their ability to operate without the need for a separate receiver, simplifying their installation and use. These sensors are highly sensitive and can detect objects at varying distances, depending on the intensity of the emitted light and environmental conditions. Their relevance in the Internet of Things (IoT) lies in their ability to integrate into automated systems, allowing real-time data collection and triggering actions based on object detection. This makes them essential components in various applications, including industrial automation, security, and smart environments, where interaction with the surroundings is crucial for the functionality of connected devices.
