SISTEM PENGONTROLAN INKUBATOR MENGGUNAKAN JARINGAN WIFI

Abstract

Been created the incubator control system using wifi network. This system can be utilized in the medical field such as infant incubators, small industries such as storage of medicinal, agricultural to the storage of tobacco and cloves and farm fields for egg hatching. System hardware consists of a temperature sensor circuit, non-inverting amplifier circuit, Analog to Digital Converter circuit (ADC) and the relay circuit. Combination the LM35 temperature sensor IC uses that have a sensitivity of 10 mV/0C. The output voltage of the IC LM35 is on analog form, then it strenghthened by the circuit of non-inverting amplifier using LM358 IC. Analog voltage that has been strengthened by IC LM358 converted into digital data using 8-bit ADC Combination 0804, then it reads by server program and the data sent to the client. From this program, client can control the set point value that has been determined then sent to the server. Set point data sent from client to server to control the lights on incubator space using relay circuit that serves as a heater. Server program for displaying the temperature data, with the default control 370C, and also processing data and storing it in the table found on the Absolute Monitoring Database. Table used to record data such as temperature, set point, time and date. Besides that, the server program used to process data and display data in graphical form with changes in temperature set point and taken each time the given period. Based on print menu that provided, data recorded on the chart can be printed through a printer. The data have been processed and then send to client programs via TCP/ IP protocol. Result from this study is generated client programs that can monitor temperature, set point control with a value of 360C, 370C and 380C, except that client programs can display graphics with the change in set point and temperature taken every time. From the results of this system design has been realized by maintaining a above room temperature (36-38) 0C with an error rate of temperature (2.6 to 2.7)% and the accuracy of the system at 97.3% working area - 99%.
