Design principles and microelectronic parts of sensor devices signal transducers (including thermo-magneto-, photo- measuring converters) meeting requirements of up-to-date low-voltage energy-efficient apparatus driven and fed through USB port are considered. It is shown that such sensors in order to providing high technical characteristics have to have possibility of high-precision functional transductions at low-voltage unipolar supply source (5 V or less), consume small power (tens of mW or less) and be compatible with USB interface.
