Cup Anemometer

In this work, a new and low-cost Arduino-Based Data Acquisition System (ABDAS) for use in an aerodynamics lab is developed. Its design is simple and reliable. The accuracy of the system has been checked by being directly compared with a commercial and high accuracy level hardware from National Instruments. Furthermore, ABDAS has been compared to the accredited calibration system in the IDR/UPM Institute, its measurements during this testing campaign being used to analyzed two different cup anemometer frequency determination procedures: counting pulses and the Fourier transform. The results indicate a more accurate transfer function of the cup anemometers when counting pulses procedure is used.

Weather Observation

Data acquisition system for barometric capacitive pressure sensor with high accuracy is present. The precision of the data acquisition system is less than 1fF, which improves the pressure sensor with high accuracy of 0.1hPa in the pressure range from 5hPa to 1080hPa. The data acquisition system consists of an AD7746 chip, an ATmega16 microprocessor, a 1602 LCD display and a pair of wireless modules. The capacitance data acquired by the AD7746 are transferred to a host computer using RS232 port via wireless module and display on the LCD in real-time. Preliminary results obtained from experiments show that this system fulfills the requirements of the weather observation and can be used in upper-air weather detection applications.
