This Instructable provides a step-by-step explanation on how to develop the app that can allow the user to monitor a travel trailer from their phone or other device using motion, sound, light, temperature/humidity, and gas sensors. This system uses wireless Arduino-based sensors, Arduino Uno and Intel Galileo single-board computers and an open source home automation platform called OpenHab. While this Instructable is targeted for the Ann Richards School Airstream trailer, the product can be used in other tiny living areas.
