Development and Application Embedded Systems and Wireless Network of Sensors to Control of Hydroponic Greenhouses

摘要

A network of hardwired conventional sensors have been used traditionally for sensing, monitoring and control of the climate in greenhouses and fertigation of the crop. However, in recent years due to the introduction of new cultivation methods, e.g. hydroponics, the number of required sensors in greenhouse installations has increased drastically and their associated monitoring and control has become complex. In addition, the extensive wiring of the sensor network has increased the requirements for system maintenance and measurement errors. The development and application of wireless embedded sensors for monitoring and control of hydroponic systems can result in reduction of measurement errors, easy expansion of the sensor network system, reduction in the cost of system installation and its maintenance and safe data transfer. In addition, the use of embedded computer systems and appropriate software can provide flexibility and reliability in measuring and controlling the parameters of hydroponic systems at reduced cost.
