The solution adopts 5.8G high-altitude or long-distance microwave radar module series.It supports to assembly in a ultra-high height such as 15m or ultra-long-distance such as 20m-30m applications.Also it can be combined with BLE module, 433 remote module,to realize light control if there have objects in set sensing distance range or not, applied in large-scale warehouses, factories, etc., to achieve the purpose of industrial energy saving.
