Abstract: An illustrative example embodiment of a device for communicating information regarding an elevator car that moves along a vertical path includes at least one sensing portion configured to be supported on the elevator car and to sense at least one characteristic of the elevator car. A transmitter is configured to transmit a wirelessly communicated output indicating at least one condition based on the sensed characteristic. The transmitter is configured to use a first transmit power when the device is at a first location along the vertical path and to use a second, different transmit power when the device is at a second, different location along the vertical path.
