A wireless interface system can interface with any one of a plurality of transducers of different types, such as pressure sensors, temperature sensors, or current probes. In the system, transducers employ substantially identical connectors with a common connecting scheme. In this manner, any transducer can be connected to a wireless interface which has the same input connection scheme. When the wireless interface is connected to the transducer, a rechargeable battery, which is associated with the wireless interface, is activated. The wireless interface then determines the type of transducer being utilized and provides sufficient circuitry as well as determining the requirements of the connected transducer. In this manner, the wireless interface, can determine the range of the sensor, and depending on the type and range of the sensor, can provide specific circuitry to be activated to supply power and read data from the sensor via common output pins.
