Afegir etiqueta | Sumari: | At the Aquarium of the Polytechnic School of the Coast (Repository), there are several fish tanks, in which pressure and temperature measurements are made naturally , causing inconvenience and errors that usually occur when operating this way. Consequently, the objective of this project is to design automatic control of each of the three tanks, as well as supervision of the indicated variables, including pH (pH is a measure of acidity or alkalinity of a solution. The pH indicates the hydronium ion concentration [H3O +] present in certain substances), all from one control site. To achieve the aim in an automated microprocessor-based system for obtaining data from temperature sensors and pressure PH of each of the tanks, which after being processed, allows corrections are effected hull design. For the interaction between the user and the system with a human machine interface (HMI ) through which the temperature , pH and pressure air entering each tank filter design is visualized , and saved the historic variables. The results of the matching test in the system operation, the sensed variables of temperature, pH and the air pressure in the system has a margin of error of deviation of plus or minus 0.2 ° C, plus or minus 0.4 units of PH and about 0.1 PSI ( PSI is called " pressure " to the extent that it relates the force applied to a surface area the same ( only applied to fluids.) Pressure is measured with manometers, barometers as appropriate), respectively, margins not affecting the biological process water accelerates the determination of the alkalinity or acidity of the water that is under the fish in the tank, as the natural state of water where fish live deteriorate, respectively. |
