Abstract :

A data acquisition node/system uses various sensors, dedicated hardware and respective software to measure and store physical signals like voltage, temperature, pressure etc. Present paper describes the design of a real-time data acquisition system, using a low cost, credit card sized computer known as a Raspberry Pi to collect various environmental data related to wind, solar, rain, temperature and humidity, which can be used for further analysis and model development. Wind direction and wind speed was obtained using a wind-vane and an anemometer by Davis. To collect rain data, a rain gauge with an ultrasonic distance module was used and Kipp & Zonen CM-11 Pyranometer was used to collect data related to solar irradiance. The temperature and humidity related data was collected using a DHT-11 sensor. Data from all the sensors was collected by Raspberry Pi using python scripts for each respective sensor and then collected data were logged and stored on a web server. Environmental data collected by our system was verified and found satisfactory.
