Energy Saving Switch With Presence Sensor

Detailed, step by step Instructions:

Do you face such situations when you leave your reading lights, table fans or soldering irons without switching them off and later realize that they were on for too many hours which subsequently jumps off your electricity bills? Well, if you have such a problem of forgetting things which probably most of you would have (including me :P), you have just found the right thing! This project will detect your presence on your work chair and then switch on and off appliances connected to it accordingly. 

The project uses an ultrasonic sensor connected to the Mediatek Linkit ONE as it's brain. By detecting the distance from the sensor to your chair, it can detect your presence as the distance will decrease when you are sitting on the chair. The relay connected to linkit one gets activated when you are sitting on your chair thus switching on the appliance while it switches it off as you leave. Thus, this project will greatly help to reduce your electricity bills as any appliance from soldering irons and hot glue guns to lights and fans can be controlled using this appliance.

The project is not very complicated and easy to make thus can be a good way to start with linkit one. There are innumerable number of modifications you can make to this project. Remember to post a feedback in the comment section below. Do post the pictures of your own project if you've made one yourself. Don't forget to follow for more great projects!
