Description: A tethered sensor is a device that is physically connected to a system or device for data transmission. These sensors are fundamental in the Internet of Things (IoT) realm, as they allow for real-time information gathering on various variables such as temperature, humidity, pressure, among others. Unlike wireless sensors, which transmit data through communication networks, tethered sensors require a physical connection, which can offer advantages in terms of stability and reliability of data transmission. Their design can range from simple electronic components to more complex systems that integrate multiple sensors into a single device. The implementation of tethered sensors is common in various environments, including industrial settings where precision and safety are crucial, as well as in environmental monitoring applications and smart home systems. These sensors are essential for accurate data collection and process control, contributing to operational efficiency and informed decision-making.
