Computer controlled, internet-aided greenhouse automation

In the present study, it is aimed to build an automation system which is more flexible, useful and meeting every kind of requirements, by eliminating insufficiencies of automation systems using in greenhouses. Control of the environmental parameters such as temperature, humidity and light, of the greenhouse can be carried out automatically or remotely. Required software and computer controlled hardware are designed for this operations.The system being developed, is designed for working with any kind of measurement (sensors, converters) and control units. Therefore, a broad spectrum electronic card and four analog, one digital input and ten digital output are designed. To obtain the flexibility, PIC16F873, a programmable micro controller unit is used with card.Control software is writen by enabling communication with the designed electronic card. In this way, all cards connected to the system, will be controlled by software or in other words by computer. Controlling software and electronic card are designed flexible, thus it is possible that any measurement unit can be connected to any desired analog input and any controlling unit to output. Collected measurement data by the controlling software has been stored in a database. In addition, its possible to reach the measurement data through web interface of the automation system.
