| Summary: | 碩士 === 華梵大學 === 電子工程學系碩士班 === 103 === In this thesis, we propose a design of closed environment nursery box, including the temperature control humidity, airflow and supplemental lighting. With the proposed system, the germination rate will increase, and seedlings will grow well in non-season.
First, we use closed environment as the structural design of a nursery box, and we can prevent the defect of traditional nursery from external environmental impacts. With this system, we can reduce pests and diseases, and also ease intense temperature change.
In the control system, sensors, including soil moisture, air temperature, humidity, and sunlight, are used to be the data source from environment, and we use heating plate, fan-pairs, plant lights, submerged motor to be the driving output of environmental control.
Finally, an experimental group and control group under the same condition of seeds and environment are established to observe the differences of plant growth between the seeds in the nursery box and the seeds in natural environment. Via the analysis results, the proposed control system architecture will be validated.
