Abstract

Thermal anemometer merupakan alat ukur kecepatan angin yang sering digunakan oleh BMKG, used this instrument to measure the wind speed environment. Thermal Anemometer have been made by arif harianto ( 2005) using series with diode and heater, this configuraton take no account of the influence of wind temperature in measurement process ( type CTA). this Appliance Weakness is wind temperature very influencing process in measurement of wind speed also have the low measure boundary. The problems overcome by using two censor of temperature LM 35. The First sensor to measure the wind speed and secondly as kompensator temperature of environment, so that the instrument can adapt to change of temperature environment. Maximum limit this measurement system is 6.9 m / s because its limitation wind source of available. While to increase respon time system at measurement proccess used Integral Proposional ( PI) Controller. Without controller (open Loop) approach the result of knowable new measurement after 50 second, by using PI controller after 15 second. Data process have done by mikrokontroller ATMEGA 16. Measurement result of this instrument is appeare in LCD character. Keyword: Thermal Anemometer, sensor of temperature LM35, ATMEGA 16, PI Controller
