Have you ever wondered why we manually get on bathroom scales to check our weight? Or maybe you want an alarm that won't shut off until you get out of bed? With our Smart Bed sensor system, you place four sensors underneath your bed and a web server is routinely told the weight on top of your bed. Our example app is using the data to make an alarm that only shuts off once the person removes themselves from the bed.

The system is four amplified load sensors connected to a Raspberry pi, which speaks to a Ruby on Rails server. Then a simple alarm app pulls real time data from the Ruby server to determine if you are on the bed.
