A final project for a smart devices class, this was a prototype of a home-automation device which could be placed over any existing light switch to monitor and control the lights in any given room while also serving as a temperature and humidity sensor. The prototype was designed to be an adaptable unit that could without requiring any major modifications to the electrical system. This device featured a Particle Photon 2 programmed in C++ being remotely controlled via one's phone using the Blynk cloud console. The device also published current and historical light activity, temperature, and humidity data to a privately accessible website ran through Initial State. The design utilized a 3D printed servo horn to actuate the light switch while still allowing for manual operation of the switch. Comprehensive documentation was also created for the device, including a user manual, developer documentation, and a detailed cost report.
