Data Acquisition of Multiple Sensors in Greenhouse Using Arduino Platform

Continuous monitoring of environmental parameters is necessary in order to achieve maximum plant growth in a greenhouse system. The aim of this study is to perform a real time data monitoring from multiple sensors in greenhouse using Arduino and Excel add-ins. DHT22 sensors, BH1750 sensor are the main sensors used in this study which give the exact value of temperature, humidity, and light intensity, respectively. Arduino Uno board provides multiple inputs analogs and I/O digitals were utilized to read the data sensor aforementioned that applied for the greenhouse. The level of accuracy of each sensor was compare to the standard device results. The results show that the accuracy of the sensors measurement is very good. This system design is real time, simple and low cost that given ability for user to monitor, collect, and to plot their greenhouse environments data in an Excel sheet.
