This paper introduced the working principle and implementation technique of intelligent passive digital display watch for two wire line by single chip microcomputer MSP430FE427 of Texas Instruments Incorporated. The current 4～20 mA which came from the sensor can be displayed in the form of physics by the LED of the watch,which can solve the problem that LCD can't display in the dark.The watch can work without power supply, display with the resolution 1/6 000 and has other features,such as high precision, flexible configuration and good stabilization.
