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