Soil moisture monitoring using near-infrared sensing technique and the Internet in a coffee plantation field
نویسندگان
چکیده
We have developed two types of soil moisture monitoring system and performed long-term test employment of these systems in the coffee plantation in Hawaii. One is a lower cost and smaller size near-infrared moisture sensor developed by the SANYO Electric (Co., Ltd.), the other is a modified system for monitoring soil information, called SIMS(Soil Information Monitoring System). We settled them in the UCC (Ueshima Coffee Company) (Co., Ltd.) coffee farm in Hawaii and tried to retrieve the observed data through the Internet.
