7. WiFi Door Sensor
You can easily build amazing useful devices such as a WiFi door sensor which ranks 7th on our list of easiest IoT projects for students. And the best part is that it won’t cost you a lot of money, too. This can be very useful if you want to keep an eye on what’s going on at home. For example, you want your freezer doors to stay shut, and with a device like this, you’ll always know if you or a family member forgot to close them. Basically, you’ll need things already mentioned in the previous project description, so make sure you buy an ESP8266 development board, a micro USB cable, a USB wall charger, and tools like a pair of pliers and a hacksaw. To create the device and connect it to WiFI, you need to sign up for an IFTTT account (If This Then That) and then download the app. Here are the rest of the instructions so you can complete your project.
