This layer contains things that make up the IoT such as sensors, transducers, actuators, smartphones, smart devices, and Radio-Frequency Identification (RFID) tags.
There can be many categories of sensors such as body sensors, home sensors, and environmental sensors based on the type of work they perform.
A Complete Guide to Understanding This Blockchain Concept
This layer is the core of an IoT ecosystem where various sensors are used to sense real-world environments.
This layer includes sensors that can monitor temperature, humidity, liquid flow, chemicals, air, pressure, and much more.
Usually, an Analog to Digital Converter (ADC) is required on a device to turn the real-world analog signal into a digital signal that a microprocessor can understand.
Actuators in this layer provide the means to enable control of external environments, for example, starting a motor or opening a door.
These components also require digital to analog converters to convert a digital signal into analog.
This method is especially relevant when control of a mechanical component is required by the IoT device.
Why This Matters for Blockchain Technology
Understanding Device layer is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
