What is Architecture of Internet of Things?

In this tutorial we are going to learn about what is Architecture of Internet of Things?

As per below image of Architecture of Internet of Things.

Here are five layers for IOT now we will learn about each layer.

  1. Sensors and Actuators

Any physical parameter convert into electrical signal is called sensors, Example – Temperature Sensor, Door Sensor etc. 

Actuators- which are convert electrical signal to motion signal with help of control signal is called Actuators, Example – Motor etc.

  • Devices – In IOT have two things Internet and Things. AC, TV, DOOR, FRIDGE, COOLER etc.

Like door is not anything which can generate the any signal so that we have to put any sensor at door that’s called DOOR Sensor.

Devices = THINGS + Sensor

  • GATEWAY –  Now our device should be connect to internet which are not possible to connect direct so that we need external hardware those will connect things to internet , Suppose that we have phone which want to connect to internet by WI-FI , Bluetooth, Cellular basically for network which can transfer the data one devices to other devices through GATEWAY like RFID, WI-FI, IR, BLUETOOTH , GSM Module & NFC etc.
  • Communication –

MQTT (MASSEGE QUIEING TELEMETRY TRANSPORT) this protocol which through data transfers at our device and specially design for IOT. This protocol is very light, It can use in BIT.

  •    CLOUD – Cloud there is all data store for devices , Like that we have Google cloud and apple I cloud. This is application of cloud ,

CLOUD – PAAS- Platform as a service

 SAAS –stand for software as a service

 IAAS – Infrastructure as a service

COMPLETE IOT –

1. SENSOR + THINGS = DEVICES

2. DEVICES + EXTERNAL HARDWARE = GATEWAY

3. DEVICES + GATEWAY + MQTT PROTOCOL = CLOUD
