In-Situ Wireless Sensor Networks for Agricultural Crop Monitoring

Architecture of CAN't

In the context of Precision Agriculture, continuous monitoring of plant parameters plays an important role. IEEE 802.15.4 Wireless Sensor Networks (WSNs) are tailored for such in-situ monitoring systems. They have the potential to record the condition of cultivated plants and transforming it into up-to-date parameter maps, which can identify potential growth- and yield-reducing factors at an early stage. Thereby, WSNs enable decision support that contributes to a site-specific, targeted, and sustainable management of agricultural fields.

In the project WSN4Crop, a automated agricultural monitoring is realized that enables a cost-efficient in-situ assessment of an important plant parameter, the Leaf Area Index (LAI). To this end, based on commercially available WSN hardware, a low-cost sensor prototype for a passive, transmission-based LAI assessment is designed and experimentally evaluated in various field campaigns (cf. Publication 2). Tailored to the specific application, a network architecture is designed that transfers the prototype into a holistic long-term monitoring system (cf. Publication 3). Finally, the potential of the implemented monitoring system for a continuous and temporally high-resolution LAI acquisition is analyzed using exemplarily realized deployments and the empirical data sets (cf. Publication 4).

Data set

The data set contains raw sensor data and additional logging information from a certain long-term deployment at experimental fields at the Institute for Crop and Soil Science of the Julius Kühn-Institut (JKI) in Braunschweig, Germany. This data includes readings from light, temperature and humidity sensors as well as link quality information (RSSI and LQI) and collected during the deployment. Further details can be found in the README.
