Abstract: This paper proposes a data acquisition system that controls an automated farmland. The information received by the sensors used in this project are being sent to the microcontroller from the sensors which processes the data collected and then opens or closes a drip irrigation system valve based on the information received by the microcontroller. The data that is being read by the sensors is also sent to the user through a GSM module, displayed on the liquid crystal display (LCD) and is stored on an memory (SD) card every twenty-five minutes. The developed system increased efficiency on the field where it was implemented. The result was then collected for the period of two (2) weeks and there were variations for different days which were due to climatic conditions. The designed system worked optimally and is fully recommended for both small-scale and large-scale implementations.

Keywords: Data acquisition, microcontroller, GSM module, SD Card module.

I. INTRODUCTION

Data acquisition systems have been in existence since the 1960s, when creators at IBM developed the first computer-hardware machines [1]. They put out their first official data acquisition machine in 1963. They called it the IBM 7700 Data Acquisition System. Just one year later, they released the 1800 Data Acquisition and Control System. Unlike the International Business Machines (IBM) 7700, this system featured a component for disk storage [2].
Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon such as soil moisture, soil temperature, pressure, soil humidity, voltage, current, etc. A DAQ system consists of sensors, DAQ measurement hardware and a computer with programmable software. Compared to traditional measurement systems, PC-based DAQ systems exploit the processing power, productivity, display and connectivity capabilities of industry – standard computers providing a more powerful, flexible and cost – effective measurement solution. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software.
