To ensure your safety (and others too!), I would advise you to carry this out only if you know what you are doing, and have had previous experience with high voltage electricity. Note: This project uses a relay, to control a high voltage appliance with the LinkIt ONE. But then came the LinkIt ONE, a board designed for wearables and IoT and so, I planned to make the above proposed project with the LinkIt ONE, with additional features, such as being able to receive the temperature and humidity, along with values from a smoke sensor which can alert me when there is a fire, or smoke present in the room.

I had initially thought of using the Arduino UNO for this project, but was unable to do so by the cost (Shields were expensive than the UNO itself). So, given a hint of the awesome features present in this board, let us proceed to the main project. And along with that, you get ample space for coding and a generous amount of RAM (for a microcontroller of its size) to execute your code, without lagging, as there is on the Arduino UNO, when used with with bigger and more complex codes. The main features of this board, which make it the perfect candidate for this project is WiFi, Bluetooth, GPS, GSM and a micro SD card slot, all integrated in a compact package, comparable to the Arduino UNO. You will certainly say there is not much difference (other than the brilliant color scheme, of course!), but when you know the actual features, you will be dazzled.

Looking at the above scene, there is a solution for this, using an Arduino UNO, along with some shields and peripheral devices (bluetooth module,etc) by using the WiFi shield, and a relay, by switching the relay on when you are about to return to your house, approximately half an hour before your arrival.īut MediaTek's LinkIt ONE can provide an even better and robust solution, considering its features. But by the time you come back, there will be absolutely no cooling left in your room and you will have to wait for probably more than half an hour after switching on the air conditioner, for it to get the room's temperature to a bearable point. You will have to switch off the air conditioner, to save electricity and cut down costs before going. Now imagine you have to go out for some time, say two or three hours. But when you are indoors, in your house or room, and the air conditioner is switched on, you do not feel the heat at all. If you have ever been to the United Arab Emirates in summer, you will probably know about the heat there.
