Due to the manual and low efficiency, poor interactivity, lack of the remote control and visual appeal of the man-machine interface for the flower maintenance, we proposed a kind of interactive intelligent virtual reality monitoring and control system for flower maintenance based on internet of things and Unity3D. It was designed and developed by using the Arduino open source hardware platform and the Unity3D engine mobile development platform. The system consists of a base station server and a

... remote station client. Base station server uses the soil moisture and DHT temperature & humidity sensor to measure the soil humidity and the indoor environment temperature and humidity. Controller controls the irrigation amount through the regulation of electromagnetic valve according to the setpoint of soil humidity when the environment temperature is allowed. Remote station client is used to achieve virtual roaming, real-time monitoring, information display and remote control function. Data transmission and exchange between the base station server and the remote station client is realized through the wireless router. System tests show that the system can monitor the growth of flowers by the three-dimensional interactive virtual reality scene, automatically adjust the water quantity, and improve the practicality and interest of flower maintenance.
