Personnel Positioning UWB Worker Card Tag VDU1511

VDU1511 is a positioning card based on UWB (ultra wide band) technology. The main control chip uses NRF52832 to control the receiving and transmission of UWB signals. DW1000 positioning chip can realize high precision positioning based on UWB TDOA (arrival time difference) by burning different firmware and cooperating with different UWB positioning base stations. The built-in acceleration sensor can intelligently switch the positioning frequency of moving and stationary personnel to optimize power consumption. The card has the SOS button for help function, which can realize the positioning of personnel in nursing homes and other security monitoring occasions.
