Nowadays, the systems mostly used to control greenhouse environment executes a fixed routine driving valves and pumps with temporization through low price programmable timers to provide water and nutrients to the seeds or buds without concern on the rational use of resources. The present work presents a Supervisory and Control System based on the Elípse SCADA Supervisory Software that is been developed at the Electrical Engineering Department of Electrical Engineering School of University of State of São Paulo at Bauru. The environment variables acquisition and the driving signals to control valves and pumps are carried by a RS485 network using MODBUS protocol. Considering the application environment characteristics all data from sensors are transmitted to data concentrators by RF links.
