IoT – How?
Time isn’t far when your coffee maker will know your mood swings better than your loved one.
Iot is an amalgamation of devices that are connected with each other. Devices acquire, process and transfer the data from their surroundings with the help of sensors, controllers and other hardware components.
These connected devices have the potential to generate a vast amount of data and traffic which can be used to provide real-time information. You can monitor the workplace and home remotely. Industries can be blessed to improve productivity and reduce cost and waste. Sensor can make the city smart to avoid congestion and help during accidents or any natural calamity.
- Sensors are an integral part of any IoT application. They are the gripping point from where innovations begin.
- Without network like internet, this isn’t possible. Therefore, it plays a crucial role in the IoT framework.
- Controller is the middle man between sensor and internet. It acquires data and commands the machine or device to function accordingly.
Controller can be of numerous types. Earlier, 90% of controller were built in C language and C++. But with time, they got diversified and now, hybrid technology is available which is both real time and lightweight. Thus, gap between developer and controller to make the hardware is bridged.
Cellular technology is one of the most widely used tech which is both general purpose and easily available. According to a survey, in 2001, 58% cities were covered by 2G which has increased to 95% with the help of cellular community.Today devices like Pi are available which is a credit card sized device, efficient to perform many desktop-like functions.
Computing has improved rigorously and is easily accessible today. Processing power is getting better day-by-day. A decade back, the processing power that NASA didn’t have is now available in your smart phone.
Real time analytics, too, has advanced a ton. Fetching records from DOS based system took minutes to hours back then which has now reduced to milliseconds.
