In this project, I used PIR (A passive infrared sensor) motion sensor to calculate your shower time. This is connected to an Arduino Wifi board that is inside of a clear acrylic case. The duration of your shower will be measured based on your motion and the shower record will be stored Adafruit.io and notify you through your email/SMS/twitter account through the IFTTT.com. I have chosen to use SMS as my report method, but I can utilize many other options like. Instead of an Arduino Uno, I only used Arduino Wifi board called, adafruit HUZZAH ESP8266, to fit and run every component in this motion glass.
For this project, I had to set up the sequence to activate the timer and send the information to myself to remind me that I should save water by taking a shorter shower!
