Design of Wireless Temperature and Humidity Monitoring Node and High Energy Efficiency Power Supply System in Seedling Room

In recent years, with the continuous progress and development of science and technology, the intelligent monitoring ability and automatic management level of the seedling room have been significantly improved. However, the number of domestic growing house control devices in our country is small and the reliability is low. Therefore, the development of intelligent greenhouse control devices suitable for our country's situation is of great significance to agricultural production, crop output enhancement and crop quality enhancement. This paper discusses the design of the precise temperature and humidity monitoring system of the seedling room, and reduces the energy consumption of the system by designing a multi-output power supply with low energy consumption.
