Prototype of Farm Environment Sensing System for State Estimation of Agricultural Crops

In this paper, we propose a system to measure the distribution of environmental information in a glass house and the transpiration flow rate of plants. A plurality of measurement devices created by combining a one-board microcomputer and sensors is placed in the farm to measure temperature, humidity, illuminance, and CO2 concentration at multiple locations. Furthermore, in order to determine the amount of water consumed by plants, the transpiration flow rate of plants is measured by a sensor. Finally, we created a growth prediction model using this sensing system, and obtained an accuracy of 0.808 in the coefficient of determination.
