Nwankwo Nonso Prince · 2011
This paper present a design and implementation of a digital egg incubator system based on Fuzzy Logic Technology. The input is obtained from LM35 which is an integrated circuit sensor that can be used to measure temperature (in oc). The output of the (LM35) is fed as an input to the Analog to Digital Converter whose major task is to convert the continuous quantity (Analog voltage from the LM35) to a discrete time digital representation / number proportional to the magnitude of the voltage, the 8 – bits binary output from the (ADC) are connected to (Port 2) of the AT89C52 microcontroller onboard the incubator, which analyses the data and provides the necessary control signal. The seven segment displays are used to display the temperature of the incubator. A Fuzzy Logic is used to control the heating element of the digital egg incubator. The problem of precision in temperature control and monitoring was analyzed and the AT89C52 microcontroller that was used to store all the assembly language of the digital egg incubator was programmed with the aid of (Top Universal Programmer).
