APLIKASI LM35DZ SEBAGAI PENDETEKSI SUHU BERBASIS AVR ATM16

Abstract

LM35DZ is a censor of temperature applied to  mikrokontroler series. Based on its specification, LM35DZ has got the limit of measurement of -55⁰ to ± 150⁰.  In daily life, temperature has got a big influence to human beings and things around them. Unstable temperature condition can cause the weakening of body endurance and broken of the electronic devices. With the growth of technology, the existence of automatic thermometer detector can maintain and keep the stability oftemperature. Temperature detector is designed using LM35DZ censor,ADC0804 converter, AVR16mikrokontroler with the output speaker and LCD. This device can detect temperature and will give information through LCD display. Heat signal will be detected by LM35DZ and changed into digital signal by  ADC converter.After that, the signal will be processed by AVR16 to be displayed through LCD and resulted a sound  on the speaker  if it is more  than 38⁰C.
