The project uses LoRa wireless technology to monitor temperature and humidity at six MTR stations from Lai Chi Kok to Yau Ma Tei on the Tsuen Wan Line.

The project uses 6 gateways and 60 TH-01 sensors, and adopts LoRa wireless technology to collect the data of each temperature and humidity sensor, centralize the data to the cloud server through the 4G signal of the gateway, and then present it to the user through a unified BMS interface. Meanwhile, the data is recorded and analyzed for a long time for the reference of the operator.
