Abstract
This article will design an intelligent exhaust system based on the characteristics of stable, practical, and efficient, which gather factory environment data by SHT20 sensors, and then use the fixed-point transmission mode of LORA to send the packaged data to relay what processes this data and transmits it to the upper computer [1]. After that, the upper computer sends the appointed threshold values of temperature and time to the relay [2] which controls the switch of the exhaust fan by judging from this threshold values. The maximum error range of SHT20 used in this design is plus or minus 4.5%, which fully meets the requirements of the system. The system has been applied to a factory in Nantong city, and the practical application shows that the system is stable, accurate, and easy to operate, which is of great significance to the realization of intelligence in the factory.
