IoToilet

The Internet of our Toilet

IoToilet is a side project using the ESP-12 as a microcontroller, currently on its first iteration. The idea was conceived from irritating inconvenience of standing up just to check the availability of the office comfort room. There were instances that the door was unlocked by a key from the outside even if the comfort room was occupied. The lack of an occupancy indicator is the cause of this dilemma. Thus, the IoToilet is born!

How it Works

IoToilet is an Internet of Things project that uses a light-dependent resistor to check the occupancy of the comfort room.

• A lighted comfort room would mean it is occupied.

It uses the IFTTT Applet service to be able to tweet in its own Twitter account, @IoToilet.

• Tweeting is triggered when there is a change in the light brightness (from bright to dark or from dark to light).
