Resumo(s)
The aim of this Master Thesis work is to create a weather station based on sensors by creating
a data acquisition system with LabView in purpose to collect data for solar collector based on
the European standard for solar collector testing. EN 12975-2(CEN 2006) offers two different
methods for characterizing the thermal performance of solar thermal collectors: The steady
state (SS) method and the quasi-dynamic method (QDT).
The process of building the data acquisition system begin by choosing thermocouples and NI
USB-6008 DAQ device to measure ambient temperature, LM35 sensor and NI myDAQ for
the inlet mass flow measurement, for the surrounding air speed we used vernier anemometer
with NI myDAQ, another thermocouple type k for surrounding air temperature measurement
and a pyranometer with NI USB-6008 for global and diffuse irradiance.
Hence,
The main action of data acquisition systems is the sampling signals that measure real world
physical conditions (voltage, current) and converting the resulting samples into digital values
that can be handled, for example, by a computer. This project describes the fundamental
concepts of data acquisition systems; in particular sensors, transducers, communication
cabling, and system configurations.
