1. Overview
TBS-223 Dual mode wireless vehicle detector is a wireless sensor using LoRaWan long-
distance wireless standard, it integrated with geomagnetic detection and microwave
technology. Using effective dual-mode joint algorithm, the detector delivers precise parking
spot detecting function and can be widely used in intelligent traffic, smart community, smart
parking and other applications.
TBS-223 is the essential elements for the latest IoT Smart parking solution, which integrate
with LoRaWan gateway and smart parking application management platform provided a
smart parking management monitoring solution. TBS-223 is compatible with LoRaWAN
protocol, can communicate with gateway which compatible with LoRaWAN protocol.
2. Working Principle
Traditional magnetometer type Smart Parking sensor is using the characteristic of
ferromagnetic material in the vehicle frame, which make disturbance to surrounding
magnetic field while moving.
The movement of the vehicle creates a short-range distortion of this field which is
measured by the smart parking sensor with a complicated calculation to determine where
there is vehicle parked or left. The magnitude of this distortion depends on the type of the
ferrous alloy, the size of the object and the distance to the sensor.
Compared with traditional magnetometer measurement and the Radar technology,
TBS-223 improve the detection accuracy and reduce the uncertain situation happen.

8. Active zone
TBS-223 is a sensitive sensor and based on different installation method, the active zone
will be changed. The below yellow zone is the suggested vehicle keep away distance, when
Vehicle drive into or left the zone, the sensor will be activated.
The parallel to vehicle installation is much more sensitive than 90-degree installation.
Generally, if using 90-degree installation, it is suggested to change the sensitivity to 7;
however, based on different situation, customer may need to fine tune the sensitivity and
position to avoid error.
