In recent years, global warming, abnormal weather and frequent natural disasters, making things difficult for traditional agriculture. Besides, Taiwan food safety crises become more serious, sinister family food events too numerous to be contained, people gradually lose confidence in food industry. But plant factory by low external influence are not afraid of natural disasters, plant and factory production of agricultural pesticides and the presence or absence of guaranteed free of heavy metal. This study is based on plant factory automation combined with Arduino build plant growth monitoring system to observe the situation and the effect of plant growth, plant sleep movement of plants, and record environmental factors. In order to control and improve plant growth situation and environmental factors, the data can be uploaded to the cloud space, remote monitoring to achieve the effect by combining internet and cloud computing.
