Description: A fault detection sensor is a device designed to identify and report faults in systems or machinery. These sensors are fundamental in the context of the Internet of Things (IoT), where connectivity and real-time data collection are essential for predictive maintenance and process optimization. Fault detection sensors can monitor various variables such as temperature, vibration, pressure, and electrical current to detect anomalies that may indicate malfunction. By integrating into larger systems, these sensors enable automated alerts and informed decision-making, contributing to reduced downtime and operational costs. Their ability to operate autonomously and communicate with other devices makes them a valuable tool in modern industry, where efficiency and reliability are paramount. Furthermore, their implementation in various industrial and commercial environments is continuously growing, driven by the need to improve safety and sustainability in operations.
