A vehicle axle temperature monitoring solution based on the Internet of Things, using Galaxy-CAS GX30H05 and GX1831 for wheel hub temperature measurement in automobiles, used to detect the temperature of the axle during long-term operation of trucks. By monitoring the temperature in real time and uploading it to the server, it reminds drivers and the company of the current working temperature of the truck wheel hub to prevent danger; The temperature sensing unit of the axle temperature acquisition node adopts a single bus multi-point temperature measurement method; The power module is powered by batteries and needs to be compatible with low-power sensors;
