Abstract: A two-sided door usage safety system for preventing door related injuries includes a housing having a front end and a rear end each having a first engagement mechanism. The housing is configured to fit through a sensor aperture in a door. A pair of motion sensors and a pair of LED indicators are coupled within the front end and the rear end. A logic chip and a battery are coupled within an inner cavity of the housing. Each of a pair of face plates has a central viewing window and a second engagement mechanism that is selectively engageable with the first engagement mechanism. The pair of motion sensors and the logic chip are configured to detect when two people are simultaneously approaching the door from either side and to illuminate the pair of LED indicators to warn the people to open the door with caution.
