Design of Mushroom Humidity Monitoring System Based on NB-IoT

摘要

The industrialized production of mushrooms in greenhouse is not restricted by season. It is an important development direction of mushroom commodity production. The humidity control in mushroom house is the central link of mushroom industrialized cultivation management. In order to control the humidity of mushroom house reasonably and improve the yield and quality of mushroom, the threshold of greenhouse humidity control and the setting of wireless sensor monitoring points were analyzed, and the humidity monitoring system of mushroom house was designed and developed based on NB-IoT low-speed and narrow-bandwidth Internet of Things technology. The monitoring system has been tested in the intelligent agriculture building of Suzhou Agricultural Vocational and Technical College in Jiangsu Province. Five glass greenhouses with an area of 100 have been tested. The test time is at the end of April. The results show that the system reduces the relative error of collecting the humidity value of greenhouse to 1% and the data transmission of each node is stable, and users can realize cloud intelligence by using mobile phones. Energy management has the advantages of miniaturization, high cost performance, high measurement accuracy and so on. It is worth popularizing and using.
