Abstract

A thermometer with sound output has been developed. The systemconsists of a temperature sensor, a microcontroller, a voice device, and aspeaker. The temperature sensor of DS18S20 will convert the temperature todigital data. The is feed to ATmega8535 microcontroller. On the otherhand, intwelve memory of voice deviceISD2590 is recorded some numerical sound signalfrom zero to nine and word of temperature unit. For reproducing the sound signalthe data from microcontroller will switch on the memory according to it’stemperature quantity. The sound electronic signal is linked to the speaker toproduce sound. The temperature is designed to operate from 24 to 350C.

Abstract

An electronic monitoring system has been created for monitoringpatients condition simultaneously. The temperature was converted to the voltageby a temperature sensor consisting of an NTC (negative temperature coefficient)thermistor and the additional circuit that its output voltage change following thechange of thermistor resistance. The number of temperature sensor circuit isused as much as ten. The coverage of temperature measurements were in therange 35oC to 41oC. The main control system was done by Labjack UE9 workingbased program that created in LabVIEW 8.0 software. The result showed that thesystem works well, seen from the accuracy value reached more than 99%(discrepancy (D) less than 0.6%) and precision levels obtained from three timesretrieval of data also amounts to more than 99% (relative uncertainty (I) less than0.6%).

Abstract

An electronic compass system with sound output have been done. Thesystem was employed HM55B Compass Module Sensor, Microcontroller AT89S51,Operational Amplifier, and IC Voice ISD 2590.The operation of the system wascontroller by the microcontroller. The signal from the compass sensor is feed toATmega8535 microcontroller. On the otherhand, in twelve memory of voicedeviceISD2590 is recorded some word sound signal from the north to the north west.For reproducing the sound signal the data from microcontroller will switch on thememory according to it’s compass toward. The sound electronic signal is linked to thespeaker to produce sound. It was concluded that the system work well since the allparameter were displayed on the monitor simultaneously.

Abstract

Abstract: An electronic system based on Atmega8535 microcontroller for food fishfeding has been done. The system was employed a RTC, a pair infrared LED andphotodiode sensor, DC motor, driver circuit, a microcontroller, and LCD display. Themicrocontroller was programmed with C language and AVR program that suitable forthe device. The system was supported by a RTC device to get the main time basesignal of the system time. All of the system was controlled by microcontroller. Thesignal from the microcontroller is send to LCD and fish food applicator. It was concludedthat the system work well well since the all parameter and action were displayed onmonitor simultaneously and the applicator.Keyword: ATMega8535, RTC, infrared LED and photodiode sensor, DC motor,applicator
