Abstract

Have been conducted a research for the measuring instrument of time. at attempt of Viscousmeter Stokes provided with displayed a value measured by pursuant to the duration time solid the hydrogen of pursuant to difference mount the viskositas dilution. previous measurement still use the stopwatch for the determination of time turned into a automatization by mikrokontroler AT89S51. Measurement conducted by using different dilution - difference mount it’s viscouse ( viscosity). censor of Prefix and time suffix use laser as transmitter and censor LDR ( Light Dependent Resistor) as receiver. network Relay used as saklar of prefix and suffix. Result of time measurement processed by using mikrokontroler AT89S51 by timer mode 1 which have been setting with the serial program assembly and result of time measurement will be presented direct at computer.Result of system examination at censor LDR as according to its characteristic, where ever greater of light hitting LDR hence resitansi and its tension small equal to 6.5 K? and 0.1 V. While for the examination of relay, it of terenergis at the (time) of getting tension power supply 5 V. So that as a whole good ambulatory system with the difference result of measurement viskositas among big ball and small ball equal to 0.09 poise - 2 poise.
