The MSP430-TMP100 measurement system is designed to operate on as little power as possible while continuously displaying the real-time temperature of the TMP100 sensor’s environment. When operated in one-shot mode, the TMP100 goes into shutdown mode after each conversion is completed and consumes a typical current of 0.1uA between conversions.  This, coupled with the energy efficient stand-by modes of the MSP430, which consume a typical 0.9uA in low power stand-by (LPM3) along with a 3.5 digit static LCD, creates a complete temperature monitor and display system capable of 0.5°C resolution while consuming less than 4.93uA total average current.
