A DESIGN OF MULTI-FUNCTION SENSOR FOR HIGH-TECH SHRIMP FARM

Abstract

High-tech shrimp farming techniques have developed strongly and brought high potential in terms of economic efficiency for shrimp farming households in coastal areas in the Mekong Delta region. High-tech shrimp farming models require strict control of water environment parameters while equipping shrimp ponds with water environment sensors is expensive and difficult to maintain. This paper proposes an effective solution for monitoring the environmental parameters of shrimp pond water by using a handheld online multi-function sensor. From there, an effective design was proposed for a multi-function sensor to monitor the shrimp pond water environment such as dissolved oxygen, PH, oxidation reduction potential, temperature, and leftover feed at the bottom of the pond. The proposed design model is compact, portable, and connected with an IoT cloud so that farmers can not only easily move, measure and monitor pond water environmental parameters online via smartphone app, but also easily operate and maintain sensor probes. By using only one multi-function sensor to measure all shrimp ponds, the cost of investing in environmental monitoring equipment for shrimp farms has reduced many times compared to the current one. Therefore, the proposed multi-function sensor has high economic efficiency, durability, and stability. It is also very convenient for farmers and easy to implement practical applications.
