ARDUINO PLATFORM APPLIED IN THE DEVELOPMENT OF A MICROENVIRONMENTAL DATA COLLECTION SYSTEM IN GREENHOUSES

Data collection and environmental monitoring in agriculture are highly complex activities, normally requiring expensive equipment. The objective was to develop a low-cost data collection system to obtain parameters related to luminosity, soil moisture, air humidity and temperature in an agricultural environment. The Arduino prototyping platform was used to assemble the Datalogger system. Functional tests were carried out in two greenhouses A1 and A2, for a period of 24 hours. The design of the system, with the use of sensor supports, allowed the collection of data without interruption and with adequate storage in the device's memory. The Arduino platform and accessory sensors proved to be perfectly applicable for data acquisition and storage in greenhouses. The developed Datalogger prototype showed a cost reduction of 600 to 3000% compared to components available on the market with similar functionalities.
