Wired Sensor Networks
Wired sensor networks are systems of interconnected sensors that use physical cables (e.g., Ethernet, coaxial, or fiber optic) to transmit data from sensor nodes to a central processing unit or control system. They are commonly used in industrial automation, building management, and critical infrastructure monitoring where reliability, security, and real-time data transmission are prioritized. Unlike wireless alternatives, they offer stable connections with minimal interference, making them suitable for environments with high electromagnetic noise or strict safety requirements.
Developers should learn about wired sensor networks when working on industrial control systems (ICS), smart buildings, or applications requiring high data integrity and low latency, such as factory automation or power grid monitoring. They are essential in scenarios where wireless signals might be unreliable or insecure, such as in hazardous locations or data-sensitive installations. Understanding this concept helps in designing robust, scalable systems that leverage wired protocols like Modbus, PROFIBUS, or Ethernet/IP for sensor integration.
