Aging - Lack of successors

In Japan

• 34% of farmers

aged over 65 years old

•Only 4% of working population are farmers

• Farmers have decreased

Safety of food - Fukushima•Fukushima nuclear accident on March 11 ,2011•Area contaminated with radioactivity

•Agricultural and marine products were affected•The increasing interest in food safety

Effect of weather - Floods in Thailand

•Agricultural damage is

　฿74,000,000,000•Huge damage has occurred in rice

• If there are systems that can monitor the water level, the damage could be reduced

Feature of Shonai Region

Located in the north-eastern part of Japan

Facing the Sea of Japan

13

Shonai is famous for growing many kinds of traditional farm products.

wind and solar power hybrid power generation system

Two fields were located within 1 kilometers

Through the above route, the data sent from Agri-server is stored in a data folder in a web server

A snow-covered Agri-Server in winter

20The server totally covered with snow, but we confirmed that it worked properly.

Conditions ofAgri-Server after winter

21

Camera and sensors were tilted by the weight of snow

Anemometer and anemoscope were bentSolar panels were broken from freezing

Higher Reliability against hard weather condition is required

24

The low cost and lower power consumption than Wireless LAN

PHP scripts are more lightly loaded Ruby

Better processing of text data faster than the database

also the capability of graph display, not only text data.

Arduino•AVR Microcontroller

•Open source hardware•Open source software

•Extensive library•Hardware can easily be mounted on the basal plate called the shield

Safety of food is important. The Consumer demands to identify where and how farm products have been grown.

It is doing various approaches that the producer, the distributor, and the distributor respond to it.

Cheap environmental monitor system is hoped for the spread in the future.

Because it is tried to measure and use the information of weather and the state of the soil for the labor for farming by research laboratories and so on.
