عنوان مقاله [English]
In the next decades, rapid population growth, increasing demand of agricultural yield and the standard living especially in the developing countries will significantly reduce water availability for agriculture. Therefore, desirable and optimal use of water resources and increasing agricultural productivity are vital. So, in this research, newly developed sensor has been designed and constructed for determining and monitoring real-time temperature, salinity and water content, with three years efforts from 1390. Environmental data measurement system using the brand REC-P55 in the field experiments showed that this system can record moisture content with accuracy less than 0.05% and validity less than 0.5% in different soil textures and depths. Moreover, the correlation coefficient for actual recorded data and REC-P55 one is 99%. Also, according to the capabilities of REC-P55, it was found that soil moisture profiles can be easily created and the results are of a high precision in comparison with the electrical resistance sensor and PR2.
