NB-IoT wireless parking lot occupancy sensor
WiiHey’s in-ground parking lot sensor enables you to monitor your parking facilities efficiently with real-time, individual vehicle, individual space data. It is the key to smart, active parking lot management.
The effectiveness of a parking lot management system is greatly relied on the detection of available parking spaces. WiiEMS offers parking lot sensing technology that can be easily tailored to your existing parking system, to monitor parking traffic, and to gather real time and precise information from each individual parking lot space.
The heart of the WiiEMS sensor is a geomagnetic sensor that measures the X, Y, and Z-axis values of the Earth’s magnetic field. As vehicles come into the range of the sensor, changes in the surrounding magnetic field occur and are detected. As auxiliary, an additional luminance sensor is added for double verification by detecting the background brightness changes when vehicles drive above the sensor.

WiiUNG supports two optional wireless communication methods -- UNB(Ultra Narrow Band) IoT technology and NB (Narrow Band)-IoT technology. Both technologies have transmission ranges of up to several kilometers in urban environments, with very low power consumption, data are then transmitted to cloud sever for further processing and delivery into the end-user’s system.
