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.

Wearable Electronics

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

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 desktop provides the user with the highest level of control over the system and its settings.

  • The tablet provides access to the key features of the system in a way resembling the desktop, and also acts as a remote.

  • The cellphone allows some essential settings modification and also provides remote functionality.

Other key connected devices include standard network devices like routers and switches.
