Design of Temperature and Humidity Acquisition System for Vegetable Greenhouse Based on Wireless Sensor

In view of current agricultural greenhouse vegetable planting information and automation needs，a wireless sensor of greenhouse vegetable temperature and humidity acquisition system has been designed using internet of things technology.In this regard，in order to obtain velue of temperature and humidity，the system was constructed from hardware and software respectively.In terms of hardware，vegetable greenhouse has many sensor nodes，so using temperature and humidity sensor nodes and wireless RF module to retrieve and transfer data automatically.In terms of software，software of master computer has been developed using integrated development environment of IAR.Finally，through test of some functions，feasibility of above development scheme in agricultural vegetable greenhouse was verified，which provided a reference for development and promotion of modern agriculture.
