Internet of Things: Technology to Look Out For - Part
Internet of Things: Technology to Look Out For Basic necessities of life? Present - Digital Era Internet : Part of everyone's life - Every moment Smart phones, Laptops: Right from smart watches to Industrial policies Irrespective of time Multipurpose - Bill payments, Ordering food, Online shopping etc.,
As per survey of International Telecommunication Union in 2017-70% of the youth is accessing Internet on a daily basis for various purposes Impact of Internet - Huge Revolutionizing the way we live
Can Internet perform everything? Example : After stepping out of the house - realizes that we forgot to switch off fan or light Can this be handed remotely?
Yes!! With the help of little sensors - Mounted on gadgets : Communicate with each other How ?? With the help of Internet - Converts normal devices into smart devices Technology - Internet of Things
Physical entities such as devices, appliances, vehicles etc., - Almost every possible gadget connected together Exchange information with each other - Makes life simpler and easy But how is that connection possible? Usage of extremely compact microcontrollers - Themselves small computers used internally by various single board computers like Arduino and Rasberry Pi
Arduino - Open source platform Freely available to use, modify and distribute Popular amongst IoT researchers Not just to control other devices - Can also send live feedback to users In the form of sensor generated data - To achieve large goals What are they?
Controlling a light bulb or fan from a smartphone Showing real-time level of water in a water tank Smart lighting solutions - Automatic switch on and off when someone enters or leaves a room Possibilities - Unlimited
MQ-2 Sensor : Gas and smoke detection sensor : Gas leakage at home HC-SR501 Design smart lighting solution Sensors Connected to Arduino board Rasberry Pi - Also used for home automation tools Ceo POHER OG N An Arduino Uno R3 board
Features: Interconnectivity All the devices in IoT network must be capable of communicating with each other directly or indirectly through a medium Heterogeneity IoT supports multiple devices Not necessary that all these devices will be of same type and specifications But, they must be able to exchange information among themselves for smooth working of system - Needs standard protocol Scalability - No limit on number of devices : Size can increase or decrease by any amount at any point of time, based on the need
