MARINELLI, Marcelo J; OTEGUI, Mónica B; ZAPATA, Pedro D  e  ACOSTA, Nelson H. Fuzzy Control of a Germination Chamber for Hydroponics. Rev. cienc. tecnol. [online]. 2015, n.24, pp.42-47. ISSN 1851-7587.

This study presents a germination chamber built for a water hydroponic system provided with a fuzzy logic based controller. The system was built based on an Arduino electronics platform where the fuzzy control program and telemetry systems lie. Also, all data from sensors are stored for future studies. The telemetry system sends the data obtained by the embedded system to two computers, one conected via a USB (Universal Serial Bus) and the other conected via BT (Bluetooth). In both cases data are stored in virtual disks. The results show that the germination chamber built has better performance than the conventional floating root system.
