Internet of Things Hardware
The hardware utilized in IoT systems includes devices for a remote dashboard, devices for control, servers, a routing or bridge device, and sensors. These devices manage key tasks and functions such as system activation, action specifications, security, communication, and detection to support-specific goals and actions.
IoT − Sensors
The most important hardware in IoT might be its sensors. These devices consist of energy modules, power management modules, RF modules, and sensing modules. RF modules manage communications through their signal processing, WiFi, ZigBee, Bluetooth, radio transceiver, duplexer, and BAW.
The sensing module manages sensing through assorted active and passive measurement devices. Here is a list of some of the measurement devices used in IoT −
S.No | Devices | |
1. | accelerometers | temperature sensors |
2. | magnetometers | proximity sensors |
3. | gyroscopes | image sensors |
4. | acoustic sensors | light sensors |
5. | pressure sensors | gas RFID sensors |
6. | humidity sensors | micro flow sensors |
Wearable Electronics
Wearable electronic devices are small devices worn on the head, neck, arms, torso, and feet.
Smartwatches not only help us stay connected, but as a part of an IoT system, they allow access needed for improved productivity.
Current smart wearable devices include −
- Head − Helmets, glasses
- Neck − Jewelry, collars
- Arm − Watches, wristbands, rings
- Torso − Clothing, backpacks
- Feet − Socks, shoes
Smart glasses help us enjoy more of the media and services we value, and when part of an IoT system, they allow a new approach to productivity.
Standard Devices
The desktop, tablet, and cellphone remain integral parts of IoT as the command center and remotes.
- The desktopprovides the user with the highest level of control over the system and its settings.
- The tabletprovides access to the key features of the system in a way resembling the desktop, and also acts as a remote.
- The cellphoneallows some essential settings modification and also provides remote functionality.
Other key connected devices include standard network devices like routers and switches.
Health- and fitness-oriented wearable devices that offer biometric measurements such as heart rate, perspiration levels, and even complex measurements like oxygen levels in the bloodstream are also becoming available. Technology advancements may even allow alcohol levels or other similar measurements to be made via a wearable device. The ability to sense, store, and track biometric measurements over time and then analyze the results, is just one interesting possibility. Tracking body temperature, for example, might provide an early indication of whether a cold or the flu is on the way.
Wearable devices could be allowed to automatically connect to devices around the home too. Perhaps you have a preferred lighting level when watching TV from a particular chair. You could turn on the TV and your wearable device could help adjust the lighting level from the connected LED lights within the room. An intelligent house might even support automatically blocking light from windows that created glare on the TV. Even the backlighting on the LCD TV screen could be adjusted and all settings optimized for saving energy, as well as creating the most favorable viewing experience. All these interactions could be done automatically, directly between devices, once the overall strategy has been set via a smart phone interface. The promise of the IoT is based on pervasive connectivity and when associated with large collections of connected devices, significant benefits can accrue.
Internet of Things Software
IoT software addresses its key areas of networking and action through platforms, embedded systems, partner systems, and middleware. These individual and master applications are responsible for data collection, device integration, real-time analytics, and application and process extension within the IoT network. They exploit integration with critical business systems (e.g., ordering systems, robotics, scheduling, and more) in the execution of related tasks.
Data Collection
This software manages sensing, measurements, light data filtering, light data security, and aggregation of data. It uses certain protocols to aid sensors in connecting with real-time, machine-to-machine networks. Then it collects data from multiple devices and distributes it in accordance with settings. It also works in reverse by distributing data over devices. The system eventually transmits all collected data to a central server.
Device Integration
Software supporting integration binds (dependent relationships) all system devices to create the body of the IoT system. It ensures the necessary cooperation and stable networking between devices. These applications are the defining software technology of the IoT network because without them, it is not an IoT system. They manage the various applications, protocols, and limitations of each device to allow communication.
Real-Time Analytics
These applications take data or input from various devices and convert it into viable actions or clear patterns for human analysis. They analyze information based on various settings and designs in order to perform automation-related tasks or provide the data required by industry.
Application and Process Extension
These applications extend the reach of existing systems and software to allow a wider, more effective system. They integrate predefined devices for specific purposes such as allowing certain mobile devices or engineering instruments access. It supports improved productivity and more accurate data collection.
