Claim 17:
18. The sensor array of claim 1, further comprising a second plurality of sensor ICs connected in series and configured to periodically take measurements and provide measurement data to the controller as serial data, each sensor IC including a transducer, a shift register a serial-data-in (SDI) pin, a serial-data-out (SDO) pin, a bi-directional ST/DN pin, a power regulation circuit configured to selectively supply power for a sleep mode and an active mode, and a clock pin for receiving a clock signal from the controller, wherein the controller is configured to provide a clock signal on the clock pin to initiate serial transfer of data from each of the shift registers of the second plurality of sensor ICs.
