This demonstration presents an approach to give students the ability to create an “Intranet of Things” to record, analyse and share environmental data using a transparent cloudlet. The Internet of Things (IoT) is an important subject for students to explore. Many commercial sensors are IoT devices, but these can be unusable in schools due to practical reasons of controlled access to whitelisted web services as well as ethical aspects of sharing children's data with third parties. We will empower children and teachers how to code and setup devices outside the school network, that can sense and record temperature, light and movement data inside the school buildings. The system allows data from the whole school to be easily shared, collated and analysed without using the Internet, but while still educating students about IoT and cloud concepts. We will demonstrate this “Intranet of Things” with live data collected from the conference venue.
