Design of multiparameter remote wireless monitoring system based on LoRa

To address the challenge of high manual measurement cost, heavy workload and difficulty in real-time collection, a multiparameter remote wireless monitoring system based on LoRa is proposed. The system uses sensors to form a terminal monitoring network, named the LoRa wireless data transmission radio to form a wireless communication network, and the serial port server connects with the host computer through TCP/IP protocol to establish a two-way communication between command issuing and data uploading. To meet the needs of temperature, humidity, and CO2 monitoring in the curved room, a monitoring network was built, and the temperature and humidity CO2 integrated sensor was utilized. A corresponding host computer software was developed based on C# to process the detection data. The operation results show that the transmission of multiparameter monitoring data is smooth and real-time. The system achieves wireless monitoring of temperature, humidity and CO2 concentration in the winding room, at low costs and high automation.
