Abstract
A wireless pump on/off system incorporates a radio receiver and an antenna. An RFID tag is carried on a float. The float can be located in a fluid whose level is to be controlled with at least a portion thereof protruding above the fluid level. Signal strength of a wireless received from the tag can be indicative of at least one fluid level, and responsive thereto a pump can be activated. The pump can be deactivated in response to another received wireless signal, loss of the activating signal indicative of another fluid level or expiration of a preset time interval.
