PLC Based Automated Irrigation System

In a developing country like India, automation plays an important role in the development and advancement of the country. In the field of irrigation, proper method of irrigation is important . At the present era, the gardeners have been using irrigation technique in India through the manual control in which the gardeners irrigate at the regular intervals. This process sometimes consumes more water or sometimes the water reaches late due to which the grass and plants get dried. Over-irrigation can increase energy consumption and water cost as well as leaching of fertilizers below the root zone, erosion, and transport of soil and chemical particles to the drainage ditches. Irrigators who monitor soil moisture levels in the field greatly increase their ability to conserve water and energy and avoid soil erosion and water pollution. The objective of this paper is to develop sensor based automated gardening system to reduce water requirement and balanced gardening in smart city projects in India. Manpower isn`t required in this system and moisture content of soil will be balanced all the time.

Development of Trainer Sensor as Media Learning Control Systems for Engine Cadets at Politeknik Pelayaran Surabaya

The purpose of this research was designed to: (1) develop sensor trainers that fit the needs of the control system subjects (2) develop sensor trainer with good performance, and (3) test the feasibility of sensor miner as media learning for control system learning at Surabaya Merchant Marine Polytechnic. This study was a Research and Development (R&D) in the field of education. The development research model used was ADDlE: Analysis, Design, Development, Implementation, and Evaluation. The instrument used in this study was a questionnaire with a four answer Likertscale. The validity test of the instrument was carried out by consulting with material experts and media experts. Instrument reliability was calculated using the alpha formula and produced a reliability value of 0.87 (very reliable). There are three aspects measured at this implementation stage, namely aspects of material quality, media operations, and learning aspects. The results obtained were for the quality of the material got a percentage of 78.76°/c, for media operations got 68,77°/c, and for learning got a percentage of 76.35°/c. Of the three percentages, a total percentage of 76,62°/c was obtained, so that the media trainer censor was declared feasible to be used as a learning media for the control system course after the feasibility test was conducted by theuser

FLUORESCENCE AND RED SHIFT OF THE PHOTOPHYSICAL PROPERTIES FROM PROTONATED SMALL MOLECULE

In this work, the fluorescence (FL) and bathochromic of the photophysical properties from protonated small molecule in cast film state have been investigated. To realize these purposes, the material of 4’,4’’’’-(1,4-phenylene bis (2,2’:6’,2”-terpyridine) (Phtpy) as a small molecule and camphorsulfonic acid (CSA) as an acid for protonation was selected. For Phtpy, its maxima absorption is 300 nm and no FL color emission. After CSA solution was added in chlorofom solution of Phtpy, the absorption spectrum of protonated Phtpy is broaden to longer wavelength with two new peaks appear at around 350 and 370 nm. Upon direct excitation at wavelength of 300 nm, the range of FL spectrum of original and protonated Phtpy is from 320 to 580 nm and from 370 to 580 with their maxima FL intensities at 360 and 460 nm. Interestingly, protonated Phtpy emits blue FL color emission. In addition, energy gap of protonated Phtpy is smaller than that of pristine Phtpy. Finally, the FL and remarkable red shift of absorption and FL spectra of protonated Phtpy will pave the way to develop sensor and other photonic devices with high performances in the ultaviolet region.

Monitoreo de nodos de sensores para el almacenamiento de datos a través de RS485

Xicotepec de Juárez is characterized by having fertile lands, which generates the existence of agricultural producers. Nowadays, producers are affected in the production of their crops mainly due to climate change, and this is because the decision making process to obtain a better product is not always done in the best way. So the proposed solution will influence decision making to generate good quality products and thus have efficient productions that avoid unnecessary losses. This research aims to develop sensor modules and their monitoring for agricultural crops in the region carried out in greenhouses, with the benefit of improving the environment and the cultivation process that is currently available, and this will be achieved with the storage of the reading of the data generated by mobile devices, using as development cards such as Arduino and Raspberry Pi

Development of Distributed Fiber Optic Sensors for Offshore Pipeline Leak Detection

Distributed fiber optic (FO) sensors have been used for onshore pipeline monitoring and leak detection applications. The use of FO sensors for offshore pipeline leak detection is still very new and requires developments to adapt the technology to such applications. This includes progressing the understanding of FO sensor performance for offshore leak detection, the need to develop requirements and procedures for offshore installation of pipeline and FO cable, and the need to design and develop sensor technology to cover long underwater pipelines. ExxonMobil Upstream Research Company (EMURC) has undertaken an extensive offshore pipeline leak detection research and development program. One of the key goals of the program is to develop FO sensor technology for offshore use. This paper summarizes the key findings from several technology development studies.
