DESIGNING RICE WARNING SYSTEM BASED ON IOT PLATFORM APPLICATION FOR NORTHERN MOUNTAINS

Abstract

The paper presents the results of research on the system that is responsible for measuring rainfall, measuring flood water levels and warning on the spot when the measurement criteria exceed the safety threshold on the river and stream systems. The ultimate goal is to create a fake system that is much cheaper than other systems with the same functionality on the market, while ensuring accuracy and reliability. In order to achieve these two factors, the author has used low-cost devices: Arduino UNO, LM2596 power, sim 900A module, SRF05 ultrasonic sensor, and IoT communication technology. With the total cost to complete the system is about 5.5 million cheaper than 1/3 of the systems currently being used such as the rainwater measuring system STPro Corp, the automatic rainwater measuring system of WATEC… Therefore the system is suitable for installation in the northern mountainous provinces to ensure the lives and property for people who are still struggling here. From the sensor values ​​sent to the Internet, these data will be stored in a database for analysis and provided to users and open up many new applications for hydrology in Vietnam today.
