We use technology to accomplish various tasks in our daily lives, in brief; we can describe technology as products and processes used to simplify our daily lives. We apply technology in almost everything we do in our daily lives; we use technology at work, we use technology for Health checkup, Treatment, communication, transportation, learning, manufacturing, securing data, scaling businesses and so much more. Technology has changed the usage system of home appliances, purchasing
system of daily need items, monitoring system of students in schools and many other activities of daily life by connecting with internet. Internet has interconnected ourdevices/appliances for communicating with each other using internet. All these devices/appliances which send data and receive data with each other are called “Internet of things“.
Home automation is an example of its use. Suppose you have left your home in hurry for office, on the way you can check the working condition of your home appliances with the help of a smart phone and simply turn on and off all appliances which are automated as per your requirement. We can give instructions to all automated machines, vehicles, appliances from one device which can be a mobile phone. Earlier everything was made manually and manpower was key source of production. With the passage of time, machines came into existence which increased production capacity and reduced manpower. Then computer came into existence and with computerization of machines margin of the error has been reduced in the machines
and accuracy in machines has reduced wastage of time and material. Now Internet of Things has improved the monitoring system of machines from far off places. Tracking devices are used in various fields for monitoring the work efficiency of machines and equipments which gives boost to production, safety of the man and material. Even the identity card of a worker will monitor his activities whether he is sitting idle or doing something.
School administration has to do a lot of work on daily basis to maintain data of absent students with the old process of attendance. Now ID cards with RFID or Low blue tooth technology will automatically detect the entry of the students from main gate and then entrance in the class and Principal/designated official of the school will receive notification of the absent students at desired time. Entry of male student in the bath room of female students will be detected with sounding of alarm and vice versa. Long checkout lines at the malls/stores are one of the biggest complaints about the shopping experience. Soon, these lines could disappear when the ubiquitous Universal Product Code (UPC) bar code is replaced by smart labels, also called radio frequency identification (RFID) tags. RFID tags are intelligent bar codes that can talk to a networked system to track every product that you put in your shopping cart. Imagine going to the mall/store, filling up your cart and walking right out the door. No longer will you have to wait as someone checks up each item in your cart one at a time. Instead, these RFID tags will communicate with an electronic reader that will detect every item in the cart and checks each instantly. The reader will be connected to a large network that will send information on your products to the retailer and product manufacturers. Your bank will then be notified and the amount of the bill will be deducted from your account. No lines, no waiting, no manpower used. In coming years internet of things is going to bring a revolutionary change in our living habits and working styles.
