Sign language is one of the commonly used medium to establish communication among disabled and common people. This paper describes an aiding device for the deaf, dumb and physically challenged people. Such people are made to wear gloves fitted with flex sensors whose resistance changes with each gesture shown by them. Flex sensor produces a voltage change and the Raspberry Pi will process and display the codes corresponding to each gesture on LCD and the sound code is heard via speaker. The device gains more versatility by establishing communication via GSM. Keywords: Sign, Microcontroller, calling, communication
