Application of Wireless Sensor Network Technology Based on Forest Ecological Environment Monitoring

摘要

The monitoring and protection of forestry ecological environment is of great significance to the harmonious development of human beings and nature. For this reason, it is necessary to study and develop a wireless sensor network technology based on standard LoRaWAN protocol, which has low power consumption and supports long time wok with one-time power supply. A data acquisition algorithm is put forward based on the sensor network. Divide monitoring area into some subregions with similar attributes through analyzing history data. Choose nodes to collect data in every subergions and dormancy others, which reduces greatly redundant data collected by sensor network and effectively monitors pollutant diffusion.
