| dc.description | Environmental monitoring is important as it manages the critical factors required for sustainable plants’ growth and development. In this thesis, the development of a wireless sensor network (WSN) monitoring system for young sago palms in mist chambers is presented. The effect of the functional system on the environment parameters monitored was also investigated. The system was set up to monitor three environmental factors i.e., temperature, relative humidity, and light intensity. The system is equipped with the functionality to record instantaneous readings at every 15-min interval using multiple sensors and control the opening for natural ventilation using linear actuators. It is also embedded with a smart alert system and an online monitoring portal. Data transmission was achieved using the Zigbee network and GPRS gateway. To evaluate the effect of the functional system, the temperature reduction through natural ventilation was analysed through computational fluid dynamics (CFD) simulation. The simulation was run using ANSYS Fluent software and was validated with experimental data. The ventilation efficacy was examined through two parameters, i.e., temperature heterogeneity (𝐻𝑡) and ventilation flow rate (𝑉𝐹𝑅). The greatest temperature reduction within the mist chamber was found to be 10.5% with natural ventilation. In conclusion, a WSN system for mist chambers in a sago palm greenhouse was successfully developed to real-time monitor the plant growing environment through data acquisition, data transmission and data visualisation. The developed WSN system is also capable of providing a suitable microclimate for young sago palms’ growth and development. | |
