The Design and Implementation of the Leaf Area Index Sensor [PDF]
Sensors, 2015 The quick and accurate acquisition of crop growth parameters on a large scale is important for agricultural management and food security. The combination of photographic and wireless sensor network (WSN) techniques can be used to collect agricultural information, such as leaf area index (LAI), over long distances and in real time.
