Performance of the capacitive moisture sensor under different saline conditions

نویسندگان

چکیده

Capacitive methods for determining soil moisture are extremely practical and easily applied in the agriculturalenvironment, but influenced by temperature, salinity type of soil. In this study, aim was to verify performanceof Moisture Sensor Porous Media when subjected saline media. The sensor under evaluation wasdeveloped at Federal University Ceará, provides measurements electrical frequencies related moisture.The capacitive porous media solutions with different concentrations potassium chloride(KCl), it seen that electrodes appear sensitive inserted aqueous withan conductivity up 4 dS/m. Adjustments RC (resistor-capacitor) circuit were tested as an alternative tolessen effect on measurements, possible generate readings electricalfrequencies ranging from kHz MHz. Tests then carried out a sandy conditions andsalinity. No significant differences using resistors constructed lessen theeffects taken sensor, whether solution or

Adsorption of arsenic on soil under different soil moisture conditions

The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...

Improvement of the Capacitive Grain Moisture Sensor

Moisture is one of the most important factors affecting grain quality in storage. The grain must be dried as soon as possible after harvesting to lower moisture to a standard level. It is difficult to obtain satisfactory measurement effect on precision in capacitive grain’s moisture measurement due to many influencing factors, such as temperature, species and weight. The data confusion method o...

Corn Moisture Measurement using a Capacitive Sensor

Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...

Germination under Saline Conditions’

Three mutant strains of Arabidopsis thaliana var Columbia were selected for their ability to germinate in elevated concentrations of NaCI. They were not more tolerant than wild type at subsequent development stages. Wild-type strains could not germinate at concentrations >125 mM NaCI. l w o of the mutant strains, RS17 and RS20, could withstand up to 225 mM, whereas RS19 was resistant to 175 mM....
