Smartphone near infrared monitoring of plant stress

Global trends in apps for agriculture

“…For apps that require input data, we found that most used simple quantitative data such as production per unit area, fertilizer rates, production costs, and geographic coordinate information. Although the potential for this type of analysis exists in agricultural apps (Barbosa et al 2016;Chung et al 2018;Cubero et al 2018;Laamrani et al 2018), only 12 apps that used digital photos as a data source were identified in 2018 (Table 1).…”

“…Digital cameras in mobile devices are useful tools for precision agriculture that can increase the range of use for agriculture apps to assist in various activities such as measuring insect damage (Machado et al 2016), evaluating orange harvest points (Cubero et al 2018), and determining the percentage of soil cover (Laamrani et al 2018). By using filters to evaluate images in the near infrared band, Chung et al (2018) demonstrated that the association of digital cameras and apps can be broadened. Additionally, some apps also aim to foster data collection through citizen science (Molthan et al 2017).…”

Aptamers for Detection and Diagnostics (ADD) is a proposed mobile app acquiring optical data from conjugated quantum nanodots to identify molecules indicating presence of SARS-CoV-2 virus: Why public health and healthcare need smartphone sensors as a platform for early detection and prevention

“…In general, part of the solution may be found in remote sensing and imaging tools (oil and gas pipelines 251 , leaves 252 , tree 253 canopy 254,255 , radiation 256 ). SEE or "sense everything everywhere" (paintbased computation 257 , sensors in fabrics 258 ) was a 'touchy-feely' mantra at the turn of the millenium buoyed by the principle of ubiquitous 259 computing 260 but stumbled in practice due to the cost 261 of computation 262 .…”
