Energy

Smart Grids

Smart grid is a data communications network integrated with the electrical grid. Smart grid technology provides predictive information and recommendations to utilities, their suppliers and consumers, and how best to manage power. Smart meters can capture real-time power consumption and allows to manage power distribution remotely.

 

 

Renewable Energy Systems

Renewable energy sources (like solar and wind) produce variable output. Variable output produces local voltage swings that can impact power quality. IoT-based systems integrated with the transformers  measures how much power is fed into the grid.

 

Prognostics

Energy systems have a large number of critical components whose health is essential for working correctly. IoT-based monitoring systems allows for the data to be gathered about these critical components. Analysis of massive amounts of data gathered by sensors can provide predictions for the impending failures.

 

Retail

Inventory Management

The inventory in a store or warehouse can be managed by using IoT. The products or items in the store can be attached with RFID tags. By using the RFID tags, the RFID reader or software can automatically show the number of items in the store or warehouse. If a product goes out of stock a notification can be sent to the store owner automatically.

 

Smart Payments

Now-a-days new types of payments are coming into picture like QR codes, NFC, contact less technologies etc. These technologies enables smart payments.

 

Smart Vending Machines

A smart vending machine contains several items. A consumer can insert money and get the item they want as shown in the image below. Several sensors can be attached to these vending machines such that whenever an item quantity is less, the owner of that machine will be automatically notified so that the owner can be arrangements to get that item beforehand.

 

Also, the vending machines can maintain the history of the consumers. So, when a consumer visits the vending machine next day, it can suggest the same item that the consumer purchased before.

 

 

Logistics

Route Generation and Scheduling

While delivering packages to various locations, different sensors can be fixed in those routes and they can be monitored remotely through an application. By looking at the data sent by the sensors, the delivery company can automatically know which routes are less congested and schedule the delivery of packages in such routes.
