Our ZGS-BT 5.8GHz Zhaga radar motion sensor is the core sensing unit of the vehicle-linked smart lighting system for rural roads, built on mature and stable FMCW frequency modulated continuous wave radar technology. Unlike traditional infrared or microwave sensors, FMCW radar can effectively filter interference from leaves, rain, fog and light changes, delivering reliable recognition of moving cars, motorcycles and pedestrians all day long without false triggering or missed detection. The detection distance is fully adjustable from a few meters to the maximum 20 meters, which can flexibly match road conditions with 20m to 40m lamp pole spacing commonly seen on suburban and country roads.

The biggest competitive advantage of this sensor lies in its integrated low-power Bluetooth broadcast module. Once the radar captures moving targets on the road, it will instantly send synchronous trigger signals to all street light controllers within a 100-meter coverage radius. This wireless linkage realizes a humanized lighting logic: all street lamps ahead of the traveling vehicle will light up in advance, forming a continuous illuminated zone to illuminate bends and dark road sections; after the vehicle passes, the rear lights will not dim immediately but maintain full brightness for a set delay time, avoiding sudden light dimming that disturbs following drivers. This working mode fundamentally solves the major safety hazard of invisible blind zones on winding rural night roads, greatly improving driving visibility and reducing traffic accident risks.
The product adopts the unified Zhaga standard interface popular in the global lighting industry. During renovation projects, construction teams do not need to remove or replace the original lamp housing, light source or power supply; the sensor can be directly installed at the lamp head, greatly simplifying construction steps, shortening construction periods and lowering overall transformation investment for municipal clients. When paired with CTW501-L NEMA LoRaWAN controller, the whole lighting system runs at only 20% standby brightness every night without vehicles, and switches to 100% full brightness only when the radar senses passing traffic. Compared with the traditional mode of keeping all street lights fully lit from dusk till dawn, the overall energy consumption of the road lighting system can be reduced by more than 70%, bringing obvious electricity cost savings every year for road management departments.
This radar sensor has an all-aluminum sealed casing with IP65 dustproof and waterproof rating, adapting to complex outdoor working environments including high-temperature summer exposure, cold winter frost and continuous rainy weather. It supports long-term 24-hour uninterrupted outdoor operation, with ultra-low standby power consumption that will not add extra power burden to lighting equipment. Its application scenarios cover rural highways, mountain tourist scenic roads, suburban industrial park access roads, village main roads and other low-density lighting areas. For engineering integrators and municipal purchasers, it is a cost-effective sensing hardware that balances safety performance, energy-saving effect and convenient installation.
