Greenhouse Monitoring with Wireless Sensor Network

Abstract

Financially profitable greenhouses are fully automated. The producer defines the monitoring limits for the ideal growth environment and then, the system controls automatically each adjustment to keep indoor climate at the optimal level. Increasing greenhouse sizes have forced the producers to use several measurement points for tracking the changes in the environment, thus enabling energy saving and more accurate adjustments. When each measurement point needs its own wire, the costs and cabling work increase exponentially. Once the measurement spot has been built, it is tedious to be relocated. Wireless sensor networks are gained ground in various industries. Agriculture and especially microclimate monitoring and controlling have many promising targets where the benefits of wireless devices can be exploited. In this M.Sc. thesis we discuss the wireless sensor networks applications for greenhouses monitoring. Moreover, we have built the system practically and assist the applicability of such wireless networks through real-side measurements. Star topology network measured temperature, humidity and irradiance -important developmental factors of the plants in Martens greenhouse research foundation. Test setup greenhouse was divided into vertical blocks and nodes monitor one block at a time. The idea of the vertical distribution was to gather information about the differences occurs in the climate between lower and upper flora. The measurement results proved the functionality and reliability of the wireless sensor network inside the dense and high moisture greenhouse.

The Landscape of Wireless Sensing in Greenhouse Monitoring and Control

“…The growth of the plants is the result of the photosynthesis process which converts water and and carbon dioxide into glucose and oxygen [1]. Plants are sensitive to the the portion of light spectrum from 400 to 700nm wavelength, or so-called photosynthetically active radiation [39].…”

Auto GMS: An Automated Greenhouse Monitoring System of Abiotic Factors for Leafy Vegetables Production

“…Cabling would make the measurement system expensive and vulnerable. Moreover, the cabled measurement points are difficult to relocate once they are installed [4]. The project will give ease in terms of monitoring the environmental factors for the system will be equipped with highly sensitive sensors to obtain the parameter values and send the notification to the greenhouse-in-charge via Short Messaging Service (SMS), store it in a storage card as back-up, display the findings in the LCD display and send the data and the findings over the cloud service in the graphical format using graphs and gauges for better visualization of data logs of greenhouse natural values.…”

Monitoring the Turmeric Finger Disease and Growth Characteristics Using Sensor Based Embedded System —A Novel Method

“…The various sensors used are LM35 for temperature measurement and PHE-45P is used to measure soil pH range. The sensor array collects the data of n-number of nodes and transmits it individually using Zigbee module [13] that are collectively received and monitored using coordinating module and LCD display [14]. The GSM (Global System for Mobile Communications) is used to transmit the data to a remote monitoring location.…”
