Water storage monitoring system with pH sensor for pharmaceutical plants

Abstract

Water is an excellent solvent and usually contains a wide variety of dissolved minerals and other chemical. Water molecules form hydrogen bonds with each other and are strongly polar that able to dissolve or suspend many different compounds. Due to this, water is used extensively in the preparation, processing and production of pharmaceutical products with stringent standards. This study focuses on the water storage monitoring system for pharmaceutical plants with pH sensor. The first step is to automate the water storage for the plant that control the level in the storage tank. The next step is to monitor the pH of water for it is very crucial as any different changes in pH may interfere with the performance of the pharmaceutical plant products. The acceptable pH range for water in the storage tank is in between 6.5 to 8.0. The data reading of the pH will be continuously monitored and if the pH is in the acceptable range the water will continue to fill the tank until the maximum water level is achieved but if the pH is outside of the acceptable range; the system will be instantly halted. Finally, is to study the relationship between water capacity and the pH of water. Thes monitoring system uses Arduino Mega (2560) as a microcontroller to control the flow of the program. The pH sensor used is SEN0161 and it is monitored by Arduino Serial Meter. Two different motor pumps are used and compared for performance and efficiency and the best motor will be duly recommended. Potentiometer is used to set the limit of water level in the tank.
