The LOCS sensor is a presence sensor for the elderly, whose enclosure, electronic support components and secondary elements of use we developed and manufactured for Mysphera. This product facilitates independence in the elderly, monitoring and recording their activity for their own peace of mind and that of their loved ones. The main objective of the project was to design a product adaptable to different environments, whose main value was simplicity of use and operation, and which would blend in with the environment to have the least visual impact on the user. In addition to housing the electronics, this product required experience solutions as well as the possibility of being placed in different positions and surfaces.
