This is a view of the Sagamihara Development Farm in July.

The tomato plants have grown to a height of about 50cm.

The red petit puyos are beginning to flower. It grows fast when the temperature is high.

The sensor is placed in the middle of the house.

Based on data from sensors measuring light, temperature and humidity, as well as the moisture content of the growing medium and the concentration of liquid fertiliser, the system estimates the condition of the tomatoes and tells you when and how much to water them to ensure maximum yield and sugar content.
