Development of water quality analysis reagents with controlled release ability by surface coating technique

Abstract

In order to realize the smart agriculture system with internet of things, we are developing a system for automatic monitoring and controlling of growing environment of crops. The system primarily consists of sensors of nutrient (nitrogen, phosphorus, and potassium) and environment (temperature, humidity, wind speed, etc.) and automatic fertilizing machine. To perform quantitative analysis of nutrient on a cultivated field, the nutrient sensors essentially require the continuously usable reagent. As a preliminary study, we performed parylene-N coating against disposable chloride analysis reagents. It was confirmed that the disposable reagents acquired the reusability.
