Hi,
Can someone help me in understanding this program. I need to try this with Labview Software.123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116/* THIS PROGRAM SENDS ONLY 1mA TO all si SENSORS [137 to 0 ]<br />TO DIFFERENTIATE<br />BETWEEN SENSORS DIPPED IN LIQUID & VAPOUR.
