Due to the vast of urban shelter forest, water shortage, and dry climate, it is difficult to achieve timely and accurate data collection, and it is difficult for the forestry management department to supervise.Combining the GSM wireless communication technology and the embedded technology, the monitoring system of temperature and humidity of urban shelterbelt in arid area of Xinjiang based on Internet of Things is designed.The system uses the temperature and humidity sensor, combined with the development and control level of the existing embedded microprocessors, to carry out long-distance wireless transmission based on GSM data research, to achieve temperature and humidity monitoring and management purposes based on mobile phones and computers.Experiments show that the system has good practicality, reliability and scalability.
