[Case Study] Water Temperature and Dissolved Oxygen Concentration Measurement System for Carp Farming Companies

IoT systems are active in carp farming, measuring water temperature and dissolved oxygen concentration in the water.

The Chūetsu region of Niigata Prefecture is a production area for ornamental koi. The main cause of death for weak fry is a lack of oxygen. When the water temperature rises, the oxygen in the water evaporates, leading to a decrease in oxygen concentration. This simple principle has been visualized. This can also be considered a smart agriculture tool. ◆ Applicable Product - Ideal IoT System ◆◆ Features - It uses an inexpensive and easily measurable dissolved oxygen concentration sensor. - Stable data collection is possible even from koi ponds installed over a wide area outdoors, thanks to LoRaWAN. - Data is automatically accumulated in Google Spreadsheet, and graphs and judgment results are displayed. ◆◆◆ Effects - It allows for understanding and visualization of the growth environment for koi in the pond. - It leverages the characteristics of LoRaWAN, which excels in wide-area communication. - Data is accumulated in Google Spreadsheet (equivalent to Excel), making data reuse easy.
