Bluetooth positioningBeacons are usually small Bluetooth wireless transmitters, which are usually powered by batteries and continuously transmit low-power Bluetooth signals. These types of devices are widely used in public places, hazardous chemical sites, mines, and other positioning and transmission models due to their low power consumption and precise positioning. The Bluetooth positioning beacon used in explosive hazardous areas should consider its explosion-proof performance and obtain the corresponding explosion-proof qualification certificate.
