Smart fLAIr
A Smartphone App for the Fast Leaf Area Index Retrieval

The continuous exploration and monitoring of bio-physical crop parameters enabled by modern sensor technology in the context of Smart Farming is crucial for a sustainable agriculture. The leaf area index (LAI) is one of the most important parameters that serves as an indicator for the vital condition of plants and is a key enabler for a site-specific management. In-situ LAI monitoring has the potential to boost decision-making support for famers and to increase crop yields and farm output.

Smart fLAIr is a smartphone application developed for a reliable in-situ LAI estimation. It provides a non-destructive, radiation-based approach using the ambient light sensor of the smartphone and offers a cost-efficient alternative to commercial plant canopy analyzers.
Without special hard- and software requirements and due to a focus on simplicity and usability, a wide user group of many scientific disciplines, interested in a feasible LAI acquisition, is addressed by this app.

Smart fLAIr also allows to collect LAI data from sensor devices deployed in the field using Wireless Sensor Network technology. Recently, Smart fLAIr is extended by a crowd sensing feature enabling a collaborative and distributed acquisition of LAIs (v4.0 Nov 2017).
