This visualization illustrates our client’s idea for a household monitoring system, able to sense temperature, smoke, and dangerous gases; the concept was actually inspired by a kitchen accident. As envisioned, this idea takes a hub-and-spoke approach, with USB-rechargeable, remote modules connecting wirelessly to a base station, which also houses two charging docks. The entire system is run by a smartphone app, and all functions are duplicated at the base station; real-time information and control buttons are displayed on OLED touchscreens on both devices. Because some applications of this system would require different sensors, the remote modules were designed with interchangeable sensor elements; an adjustable, focusing lens element, designed for pinpoint temperature measurement, is shown here.
