“…Since the operator cannot see the furrows as they are immediately closed after seeds are dropped, it is unknown if all seeds are properly placed. Another common problem is seed delivery tubes getting clogged from damp soil and residue accumulation, causing seeds to back up Kumar and Kumar (2023) [5] . Overcoming these issues would increase sowing mechanization and enable more effective subsequent operations.…”

This research developed and tested an embedded laser diode detection system to sense seed flow and detect blockages in seed delivery tubes on seed drills. A model was designed to evaluate the system for a single furrow opener. The detection system used a laser module and receiver module positioned across the seed tube to sense interruptions in seed flow. An Arduino controller activated an alarm and LED indicator when a blockage was detected. The system was tested at tractor speeds of 3, 5, and 7 km/h and seed rates of 90, 100, and 110 kg/ha. Performance metrics evaluated were detection accuracy, false alarm rate, and alarm response time. Results showed the blockage detection system had 100% accuracy in detecting blockages, unaffected by speed or seed rate. The false alarm rate was low, ranging from 0.3 to 1.5 alarms per 100 data points. Higher speeds and seed rates increased the false alarm rate slightly. Alarm response time varied from 10-26 seconds depending on operating parameters. The developed laser diode system accurately and reliably detected seed tube blockages under different operating conditions with minimal false alarms. The system provides real-time feedback to the operator to take corrective action and prevent yield losses from unseeded areas during blockages.

“…Concerning the molecular structure, the nonsubstituted parent coumarin is nonfluorescent or very weakly fluorescent. In contrast, the introduction of electron‐donating substituents, such as amino (NH 2 ), dialkyl‐amino (NMe 2 ; NEt 2 ), hydroxyl (OH), or methyl (Me), in 6 or 7 position, and of electron‐attracting substituents, including trifluoromethyl (CF 3 ), carbaldehyde (CHO), or cyano (CN) in 3 or 4 position, generally leads to strongly fluorescent substituted coumarins . It is also well‐documented that coumarin derivatives can be used as laser dyes and as fluorescent probes of heterogeneous inclusion systems …”

Because of their important fluorescence properties, coumarins are widely applied in sensing devices. In this paper, the electronic inductive, mesomeric, and electromeric substituent effects on the electronic absorption and fluorescence spectra of 11 substituted coumarins, including NH 2 , NMe 2 , NEt 2 , OH, CF 3 , CH 3 , COOH, Cl, and Br substituents, have been quantitatively studied by means of structure-reactivity relationships. We have applied the Hammett, Brown-Okamoto, and Yukawa-Tsuno correlations to the coumarins electronic absorption and fluorescence spectra wavenumbers and Stokes shifts. The Stokes shift of coumarins decreased when the electron-donor inductive/ mesomeric power of the substituent increased. This Stokes shift decrease was more pronounced when the solvent polarity increased, which might be explained by the electromeric effect increase.
