Deep Slumber, codename ISA, is a program made for the arm MBED during Hack The Burgh 2018 that analyses light, temperature, humidity and CO2 levels in a room. It uploads this information onto an SQL server through a rest API, providing the necessary environment for data processing. Further improvements we hope to provide are the regulation of said parameters by wifi connection to electric heaters, wifi enabled controllable lightbulbs and other iot gadgets as well as a website that will provide recommendations for sleep cycle improvements.
