Design and Implementation of WSN-based Warehouse Temperature Sensor Monitoring System

China is a large agricultural country. As an important part of the national economic foundation, the scientific storage of grain is particularly important in the process of grain production. This system uses STC89C52, nRF24L01, DHT11, etc. to form a WSN-based wireless temperature and humidity sensor monitoring system. The system monitors the humidity and temperature in the granary in real time. If the set point is exceeded, it will give an alarm. The timeliness and accuracy of environmental monitoring data on granary management will be improved, and human resources will be saved.
