IoT device architecture
1.Sensors/Actuators: Sensors or Actuators are the devices that are able to emit, accept and process data over the network. These sensors or
actuators may be connected either through wired or wireless. This contains GPS, Electrochemical, Gyroscope, RFID, etc. Most of the sensors
need connectivity through sensors gateways. The connection of sensors or actuators can be through a Local Area Network (LAN) or Personal
Area Network.
2. Gateways and Data Acquisition: As the large numbers of data are produced by this sensors and actuators need the high-speed Gateways and
Networks to transfer the data. This network can be of type Local Area Network (LAN such as WiFi, Ethernet, etc.), Wide Area Network (WAN
such as GSM, 5G, etc.).
3. Edge IT: Edge in the IoT Architecture is the hardware and software gateways that analyze and pre-process the data before transferring it to the
cloud. If the data read from the sensors and gateways are not changed from its previous reading value then it does not transfer over the cloud,
this saves the data used.
4. Data center/ Cloud: The Data Center or Cloud comes under the Management Services which process the information through analytics,
management of device and security controls. Beside this security controls and device management the cloud transfer the data to the end users
application such as Retail, Healthcare, Emergency, Environment, and Energy, etc.

M2M to IoT
Introduction:
•Each machine in embeds a smart device
• Device senses the data or status of the machine
• Performs the computation and communication functions
• A device communicates via wired or wireless systems
• Protocols: 6LowPAN, LWM2M, MQTT, XMPP
• Each device assigned 48-bits Ipv6 addresses.
Machine-to-Machine (M2M) to IoT
• Technology closely relates to IoT which use smart devices to collect data that is transmitted via the Internet to other devices.
• Close differences lies in M2M uses for device to device communication also for coordinated monitoring and control purposes
M2M Application Areas
• Connected Cars for Safety and Infotainment
• Remote Monitoring
• ATMs/Point of Sales Terminal Connected for centralized Security
• Remote Monitoring, Trucks Fleet Management

Difference between M2Mto IOT
IOT M2M
IoT stands for the Internet of Things. M2M stands for Machine-to-Machine communication
Devices include objects that are responsible for decision-
making processes.
In M2M, there is a limited amount of intelligence observed.
IoT has used internet protocols like FTP, Telnet, and HTTP. Communication technology and Traditional protocols are
uses in M2M technology.
The connection of IoT is through the network and using
various types of communication.
M2M uses a point to point connection.
It has a wide range of devices, yet the scope is large. It has a limited Scope for devices.
It has Business to Consumer (B2C) and Business to Business
(B2B).
It has Business to Business (B2B) communication.
In IoT, data sharing depends on the Internet protocol
network.
In M2M, devices may be connected through mobile or any
other network.
IoT technology supports Open API integrations. In M2M technology, there is no Open API support.
Big Data, Cloud, Smart wearables, and many more. Data and Information, sensors, and many more.

IoT in SmartHome
A smart home system can be something that makes our life quite easy. Starting from energy management where the power controls
system in the AC appliances where we use the thermostat, all this is managed to cut down the power consumption that's taking place. A door
management system, security management system, water management system are the part of this as well. Still, these are vital things that stand out
in the smart home system. The limitation of IoT in smart home application stops where our imagination stops. Anything that we wish to automate
or want to make our life easier can be a part of smart home, a smartphone system as well.
Architecture
• The Physical layer consists of devices are to be controlled
• The data link layer consists of IoT Gateway router, device manager and various communication
protocols
• The raspberry pi is used as IOT gateway which communicates to personal computer or smart phones
by means internet in the network and transport layer
• The application and presentation layer consists of web portal which is nothing but designing a
web page by which we can control the various appliances
• The appliances can also be controlled by creating an app in mobile phone which is similar to web portal

Smart Agriculture
Internet ofThings (IoT) is latest technology for smart farming to enhance efficiency, productivity and resolve various issues present in
agriculture. IoT network consist of various sensor node which is used to monitor soil acidity level, temperature, and other variables
