Otomasi pada Simulator Green House dengan SCADA Berbasis Web

Abstract

Graphical abstract Abstract Green house is a building that can modify the climate in accordance with that required by the plant. The green house system works best if it is equipped with an automation system that operates without the need for human assistance. This system consists of light sensor, soil moisture sensor, air humidity sensor, and temperature sensor. Soil moisture sensors, air humidity sensors, and temperature sensors have minimum value limits and maximum limit values. In this study, a web- based SCADA application is designed on a greenhouse simulator. PLC is used to monitor every sensor condition and control the green house simulator plant to keep it in the desired condition. PLC is connected to SCADA to monitor its controlling process and can be accessed through web browser using smartphone. From the results of observation data, output and input in SCADA happened delay time approximately for 3.195 second because happened process update time from SCADA to PLC. In addition, the first time to access SCADA via web browser will take 47.86 – 52.7 seconds because there is a process of uploading SCADA images to the folder cache for display in the web browser.
