Abstract: In Automatic Weather Stations (AWS), data loggers are used for recording and displaying the output obtained from various sensors. In the paper, a data logger is designed and developed using MSP430F5529 launchpad, Node MCU section in wake up/sleep mode, a Resistance Temperature Detector(RTD) circuit and a power supply. Energia and Arduino software is also used for developing and uploading the code on the MSP430F5529 microcontroller and on Node MCU respectively. During designing of data logger the inbuilt Real Time Clock(RTC) is activated using RTC library which keeps track of time and date. The paper also presented cloud computation using Global System for Mobile communications(GSM) and WI-FI module for continuous monitoring of output taken from a RTD sensor integrated with designed data logger in real time. In the paper mathematical calculations are described for calibration of Analog-to-Digital Converter(ADC) MSP430F5529 which is used in development of data logger. The paper also presented hardware implementation results of developed data logger and with the use of microcontroller in sleep mode, the current consumption decreases from 10mA to 6mA and hence power consumption of the data logger from the battery is minimized . Therefore data logger can be made to work for a longer duration of time with higher efficiency.
