Development of a rainwater harvesting monitoring system for agriculture

Abstract

Rainwater harvesting is simply collecting, storing and purifying the naturally soft and pure rainfall that fall upon the roof. Water resources management play an important part in agriculture development. It is necessary in areas having significant rainfall but lacking in centralized government supply system. It is also suitable to be implemented in areas where good quality fresh surface water or groundwater is lacking. Hence, this project is developed to enable the process of harvesting rainwater for agriculture is been monitored where the data of water collection in tank will be sent to the database for display, storing and analysis purpose. The proposed project will use water level sensor to sense the level of water in the collection tank and the respective valve will response to activate according to the water level. This system also can perform a water treatment and filtration for making sure that the water is clean, and the PH is suitable for agriculture. This project will use Arduino UNO as the controller to control the whole system operation. The information from the sensor is transferred via WI-FI to the database. The result shows that the system is managed to perform the collecting and storing process with sensor error range of +-0.01% for the real reading from the main tank and +-0.1% for the other tank. In addition, the system will allow remote monitoring where the user can trace back the data of the water collection for further water management process.
