Abstract

In this research, design of temperature control system has been made for Ultrasonic Assisted Extraction (UAE) equipment. The system consisted of elemen pemanas, temperature, sensor such as Resistance Temperature Detector (RTD) sensor, relay, microcontroller and computer interface. Microcontroller that used in this system is ATSAM3X8E microcontroller that connected with computer interface as the temperature data viewer that is using Borland Delphi 7. Temperature controller could be built by RTD sensor through computer interface so it could save and show the data in MySQL database. This system ca be applied as temperature controller system for extraction equipment. From this research’s result showed system that has been built can measure and control temperature using RTD sensor with the error’s value in measurement is 0,04oC. From the controlling system testing’s result with given set point is 35oC can be known that tis controlling system has delay until it started which is for 6 minutes with the control stability’s condition 97,09% and error value 2,91%.Keywords: temperature, controller, RTD sensors, database, MySQL

Abstract

In this research has built a data delivery system of environmental parameters from Raspberry Pi into a webserver database for monitoring temperature, humidity, and light intensity in realtime, which used two Raspberry Pi as the two sensor nodes. Data from measurement of temperature, humidity, and light intensity of the sensor node is transmitted into the webserver via the mobile network, then the data is stored in a MySQL database, then the data is displayed in the form of websites. Applications to display the information of temperature, humidity and light intensity are made in the form of web programming with PHP and HTML discussed. With the appearance of the web is expected to facilitate the users to access through related information anywhere and anytime with the terms connected to the network internet. from this study, obtained results Raspberry Pi is able to transmit the observed data well into the webserver with a minimum data transmission delay of 1 second and 12 second maximum delay for a sensor node-1 and minimum delivery delays 1 second and 13 second maximum delay for sensor node-2.Keywords : Raspberry Pi , webserver, PHP, MySQL

Abstract

Environment is a system that greatly affects the growth and development of organisms. In this earthly life, the environmental factors such as temperature, humidity and light intensity is an element which greatly affect humans, animals and plants to be able to adapt to its environment. Pollutants in the environment will be different in a place where others because of their conditions of temperature, humidity and lighting that will bring great influence in the spread of pollution, both in the local scale (the environment) or regional scale (environmental and vicinity). The effects of air pollution is the result of adverse impact on the environment, human health, and many living things on earth. Air pollution is a disorder that most complaints by the people. By making measurements of environmental parameters monitoring tool with LDR sensor for measuring changes in light, and DHT11 to measure changes in temperature and humidity that will be processed by the Raspberry Pi which is then displayed on a 16x2 LCD interface and stored in the database. Expected to monitor environmental parameters in real time. Some of the variables resulting from the environmental parameter measurement system with Raspberry Pi as a node such as temperature, humidity, and light intensity in the environment. The results of the data obtained by the sensor readings performed by the Raspberry Pi has a fairly good accuracy of ±  C for temperature, ± 5% RH for humidity, and ± 4,3 Lux intensity. The result shows that the system is running well. Keyword : LDR Sensor, DHT11, LCD 16x2, Raspberry Pi, Database
