To allow for wireless keypads, remote switches, motion sensors, et cetera, an RF protocol is also defined. X10 wireless devices send data packets that are nearly identical to the NEC IR protocol used by many IR remotes, and a radio receiver then provides a bridge which translates these radio packets to ordinary X10 power line control packets.
Public buildings such as hospitals frequently save energy by using motion detector switches, also known as occupancy sensors. The occupancy sensors can also be used in residential applications such as in bathrooms, garages, and hallways. [14] A wireless light switch provides remote control of lighting using a hand-held transmitter.

A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Zero speed switches (ZSS) also known as Speed Actuating Sensing Switches [1] are used to detect whether a rotating shaft is turning (even at very slow speeds) [2] in various machines, conveyors, power plants, and in industries involving the production of cement, sugar, textiles, paper, etc. Zero speed switches mainly use electromechanical, electronic, or magnetic proximity technologies.
