The invention discloses research and design of an intelligent greenhouse system based on LoRa and cloud platform Internet of Things new technologies, and relates to the technical field of greenhouses. The intelligent greenhouse system comprises a greenhouse layer, fixed columns, a soil nutrient detector, a temperature sensor, a humidity sensor, a CO2 concentration sensor, a light intensity sensor, a data conversion module, a master controller, a LoRa communication module, a cloud storage platform, a wireless communication module, terminal equipment and a driving module; and the top of the greenhouse layer is fixedly connected with a connecting box. According to the system, more greenhouses can be controlled and known through the LoRa communication module, data sharing among planting farmers is realized, generation of greenhouse environment big data is facilitated, installation by workers is facilitated, the system is more stable in the use process, collapse caused by severe weather is avoided, plants can be automatically sprayed and watered, manual operation is not needed, labor force is reduced, and meanwhile the irrigation efficiency is improved.
