http://img212.imageshack.us/img212/334/pcbfrontnv9.jpg http://img212.imageshack.us/img212/4396/pcbbackpd1.jpg I think its a pressure sensor but I dont know what type exactly.. on the component 9098 and N103 is printed but googling it leads me to nowhere.. It has only three pins(where two pins are in continuity) and two of the pins is connected to a quad Input Norgate.. and one output pin of this NOR gate leads to an MCU.. Its from a blood Pressure device.. Appreciate any input.. thanks.. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
