IoT Projects | IoT Project Ideas for Engineers

IoT has been all the rage over the past couple of years. The extensive use of sensors and wireless connectivity among devices has increased to the trend. The increase brings in turn, easily available technology for hobbyists to explore and create awesome IoT Projects. Connecting everything to everything seems like a good idea. For e.g. how would you like to control your air conditioner from the comfort of your bed when you forget your remote in the other end of the room. These IoT based Projects can be used for final year projects also. We discuss similar IoT projects included here.
