Katsuyuki Tanaka, Mizuki Murase, Katsuhiro Naito · 2018
Field sensing systems for agricultural usages are a new trend to increase agricultural production due to the downward price trend of sensor devices. Recent systems employ short range wireless communication technologies such as WiFi, IEEE 802.15.4, Bluetooth etc. WiFi is a suitable solution when an existing network is available in a field, and IEEE 802.15.4 is employed in mesh networks. Bluetooth attracts attention in smartphone sensing because it is suitable to reduce power consumption in mobile devices. Smartphone sensing is a new data collection scheme. Smartphone sensing application usually consumes energy to collect data continuously because it runs as a background process. Therefore, users request smart data collection scheme to reduce excessive consumption of energy and to avoid the conscious operation of the application. This paper develops Bluetooth Low Energy (BLE) based automated data collection scheme in agricultural measurement system. The developed scheme utilizes a smartphone to realize automated measurement information collection from sensor devices. The demonstrations show the special BLE based sensor device, a data collection application, and a browsing application.
