Kamogawa Agricultural Sensor Network

About This Project
This project is a collaborative project between Tokyo Hackerspace, Keio University, and a cooperative of farmers in Kamogawa.

Hardware

 * Chumby Hacker Board
 * Features: Linux based board. Can be used as gateway to cellular or satellite modems as well as WiFi/Ethernet networks. Excellent communications support, scripting capability, CRON jobs, many people in Tokyo Hackerspace familiar with Linux
 * FreakLabs Low Power Wireless Boards (not yet available)
 * Features: Low power, power supply with solar cell/supercapacitor + rechargeable NiMH batteries, 900 MHz wireless 802.15.4 radio, Arduino based
