SMART REAL TIME EMBEDDED ARDUINO BASED DATA ACQUISITION SYSTEM

Abstract

In this paper, an effort has been made to design and develop a smart real time embedded Arduino based data logger for indoor and outdoor environment. The present work has been concentrated to environmental parameters such as temperature, humidity and solar insolation. The data logger is proposed to be developed with the use of Arduino Uno based on ATmega328. The Arduino Microcontroller board is used which has inbuilt ADC and other peripheral circuitry necessary for operation. The physical parameter is sensed by the sensors and is converted into analog signal. This analog signal is fed to the Arduino board ADC pins which is then converted in to an equivalent digital quantity and is further processed in the microcontroller. The raw digital signal or processed signal out of microcontroller may be displayed on the LCD display or it's saved in a database or even at the same time this data is sent to computer through the USB serial port. The serial port data is then accessed and is imported in Microsoft excel for computation and graphical representation.
