The hardware design and operation of a batterypowered microcontroller-based data acquisition system (herein referred to as the DAS) for unattended remote measurements are presented. The system was designed around the ST62E20 8-bit microcontroller and applied for solar radiation monitoring. The measurement system uses the SolData silicon-cell pyranometer as(More)
A portable and user-friendly weather monitoring system based on the PIC16F876 microcontroller is described. This instrument measures three parameters: temperature in the range from -10 to +70 degrees C within +/-1 degrees C using an LM335 temperature sensor, wind speed from 0 to 10 m/s within +/-0.1 m/s using a heated bead thermistor, and solar radiation(More)
