This project is designed an effective TudungSaji is able to maintain the food warm and to protect food from pests like flies and rats. Smart TudungSaji uses an Arduino microcontroller to produce an automated function. The main parts of this project consist of chassis, 2 sensors which are temperature sensor LM35 and limit switch sensor as an inputs, the ATmega328p microcontroller and 2 bulbs as an outputs. This is to ensure the warming process operates more efficiently and effectively. The algorithm is developed and implemented with Arduino Uno. It is really practical for human, especially working woman to make their life simpler. This project helps people to keep their food warm and it is portable to bring anywhere. The performance of this project was validated with the simulation circuit using Proteus 6 Lite, and the results and findings from conducting experiments on the prototype. The bulbs are activated by the LM35 sensor detected temperature below 60 o C.Then, the bulbs will automatically off when temperature reaches upper 60 o C.This project uses 240V 100W bulb as a heating element. It can be improvised by replacing bulbs with thermistor coil. The thermistor coil can produce more heat energy because of the material of the coil, for example in the oven. Keywords: ATmega328P microcontroller, LM35 sensor, arduino, temperature, proteus 6 lite. INTRODUCTION A traditional TudungSaji is a food cover which mostly used by the Malays to cover their foods. Nowadays, the usage of TudungSaji is used to prevent food from the flies and rat. But unfortunately, it cannot maintain the temperature of the food. In theory, the quality of food must be always warm. To ensure the freshness of the food is better, it must keep the temperature around the food. Based on this problem, there are an ideal to create an automatic temperature control system technology to replace the traditional TudungSaji. Based on this problem, there is an idea to create an automatic temperature control system technology which applied to the traditional TudungSaji to become innovative, more effective and useful. A field of study to make an innovative TudungSaji was applied concept of an automatic temperature control system technology. Today, many researchers focusing on an automatic temperature control system application in different fields will gain the benefits. For example, application of PID Control and implementation of continuous PID controller in Siemens PLCs [1], an automatic temperature control system for smart fan [2], automatic temperature controller designing a data logger for a slow cooker [3],automatic room temperature control by using Fuzzy Logic Control (FLC) [4], design of automatic temperature control circuit module in tunnel microwave heating system [5],a precision temperature controller by using embedded system [6],an automatic temperature control system by using Zilog’s Real Time Kernel (RZK) can be used to control varies devices to maintain a temperature [7],a design of automatic temperature control system for the dyeing machine [8],designed an automatic temperature control (ATC) system to arise the stability of laser diode (LD) [9],the design and implementation of digital temperature measurement and automatic control system [10].There is also a case study of automatic temperature control system on diagnosable discrete event system design [11]. This paper proposes a new invention of Smart TudungSaji for various applications. It has an automatic operation using the Arduino microcontroller. It uses a unique design such as 2 light-emitting diode (LED) bulbs and 2 sensors. This is to improve the function to become more efficient and effective way to maintain the food temperature is always warm. This project provides a comfort for human’s life, easy to use and practical especially for career women. It also really helps to maintain quality and freshness of the food. Finally, this project can save power energy where it only functions when the temperature around the food below 60 o C. METHODOLOGY This project presents the design, construction, development and control of an automatic temperature controller system that applies to the Smart TudungSaji. The idea is based on the problem that happen in human life nowadays by improving the traditional TudungSaji. The block diagram of the system is shown in Figure-1. The integrated system of Smart TudungSaji consists of a temperature sensor LM35 for input, the Atmega 328p microcontroller for data interpretation and 2 bulbs as the output. The LM35 sensor is for object detection. The microcontroller uses the information provided by the
