Sensor foliar para irrigação

Abstract

The use of low-cost sensors and technologies has made a difference in several areas, for the solution of problems that were previously supported by costly and ineffective decisions. With the objective of sensing, that impersonality, impersonality and result in the effectiveness of assertiveness, and through the advancement and popularization of computational languages, it was possible to develop an electronic system to estimate the need for water from the plant. An Arduino Nano device was used in conjunction with specific modules in the development of a leaf sensor to capture electrical tension in the leaves of plants generated by the electrolytic fluid movement and the environment action, besides of being modified by different amounts of water in the plant. An Arduino Nano device was used in conjunction with specific modules in the development of a leaf sensor to capture electrical tension in the leaves of plants generated by triboelectrification, and modified by different amounts of water in the plant. The objective was to measure the tension in the leaf using the Vigna Unguiculata culture in different irrigation depths. The experiments were evaluated in the agricultural and environmental engineering shed at the University of Rondonópolis, with monitored temperature and relative humidity. Arranged in a completely randomized design, with 4 treatments and 5 repetitions totaling 20 experimental units. The results showed a trend in the increase of the tension in the measurements according to the increase of the irrigation offered to the plant, observing considerable variation between the treatments, demonstrating the effective functioning of the proposed sensor.
