ENVIRONMENT HOMEOSTASIS MEASUREMENT DEVICE WITH ENVIRONMENTAL ELECTRICAL-POTENTIAL AS INDICATOR, ENVIRONMENT HOMEOSTASIS EVALUATION METHOD, AND AUTOMATIC FEEDING SYSTEM USING ENVIRONMENTAL ELECTRICAL-POTENTIAL

Title:

Document Type and Number:

WIPO Patent Application WO/2018/127989

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing: a technology that enables the homeostasis capacity in environments such as soil or in water to be continuously monitored; and a technology for predicting and quantifying the feeding amount for fish and other animals being raised in an environment, on the basis of the measurement results of the homeostasis capacity in the environment. As a means for solving the problem, provided is an environment homeostatsis measurement device which includes a potentiometer comprising an FTO electrode or an ITO electrode. Also provided is a feeding system comprising: a potentiometer that comprises an FTO electrode or an ITO electrode and that is disposed in the bottom material; a feeding device that supplies feed into water; and a control unit that controls the feeding device so as to adjust the feeding timing and/or feeding amount on the basis of the value of the potential measured by the potentiometer.
