Internet of Things (IoT), hardware components serve as the fundamental blocks upon which the entire system relies. IoT hardware design plays a important role in designing efficient, reliable, and secure IoT solutions. These hardware components, carefully selected and integrated, give IoT devices their unique capabilities.
1. Sensors and Actuators: At the heart of IoT hardware
design are sensors, akin to the sensory organs of IoT devices, gathering data from the physical world. These sensors encompass a wide range, including temperature sensors, motion detectors, and humidity sensors. Actuators, on the other hand, empower IoT devices to execute physical actions based on the collected data, enhancing their utility and responsiveness.
2. Microcontrollers and Processors: Serving as the brains behind IoT devices, microcontrollers and processors are responsible for data processing, decision-making, and managing communication. IoT hardware designers must carefully select these components based on factors like processing power, energy efficiency, and compatibility with IoT communication protocols.

These IoT hardware components alongwith printed circuit boards (PCBs), providing a physical platform where all elements interconnect. Effective IoT hardware design entails optimizing PCB layouts to reduce interference, ensure signal integrity, and conserve space. Additionally, robust security features, user interfaces, power sources, and consideration of environmental conditions are critical aspects in the holistic development of IoT hardware.
