8. WorkingPrinciple
8.1. Working Principle
The frame and shell of a car are made of ferromagnetic material (various types of steel),
which make disturbance to surrounding magnetic field. According to this characteristic,
the parking sensor determines whether there is a car in the parking space by sensing the
magnetic field change. With build-in dual-sensors (geomagnetic sensor and microwave
sensor), powerful signal analysis and processing algorithm, the detector offers enhanced
information, especially acquire complementary and optimization to the reverse sensitivity
characteristics of chassis with different height.
Compared with traditional device with single sensor, TBS-201 can greatly improve the
detection accuracy and reduce information loss. The detection mechanism is show as
below.
1) Geomagnetic sensor detects the magnetic field lines which distorted by ferrous
metal of the vehicle, magnetic field strength obtained as the vehicle presence and
movement with the magnetic sensor.

2) Microwave Radar module emits wireless modulation wave and receives the
reflective signals to determine if the parking spot is occupied and vacant

8.2. Wireless Communication Working Principle
With build-in wireless transmission module, TBS-201 can communicate with LoRaWAN
gateway and smart parking application server located in cloud or in local.

9. Installation 
9.1. Installation requirements
1. Please try to install in the daytime and finish the installation as soon as possible.
2. Please pay attention to road safety and wear orange or other color clothes.
3. Tool:
a. Ruler: Measure the installation position and the hole depth.
b. Marking pen: mark the installation position.
c. Drill: Drill holes on the ground at the installation position.
d. Cleaning brush: clear sundries in holes.
e. Scoop: mixing cement, marble glue and curing agent.
9.2. Installation Steps
1. Product Check
Take out the product and make sure appearance is not damaged. Check if the label
pastes tight on the product and label information (include the DevEUI and other

Note: To restart or calibrate TBS-201, place the magnet in the groove at the top of the
device and stay for 1~5 seconds, then move away.
2. Drill hole
a. Mark the installation position
According to the design of parking space, select the installation position and mark the
position, provide a code for the parking space. Usually the device is installed in the middle
of the parking space. Shown as figure 4.

c. Clear the sundries and fill the hole with cement
Clear the sundries in the hole, put water, quick dry cement to the hole and stir evenly.
d. Place device.
Put the device into the hole, compact the cement, make sure the device surface is aligned
to or a bit lower than the road surface, finally remove the extra cement.
Note:
 Make sure cement do not cover the TBS-201 surface and the spiral slit. the spiral slit
is shown as the figure 6. Once the spiral slit is sealed with cement, the device will be
hard to remove for device maintenance or replacement.

Figure 6. the spiral slit is marked in red circle
 Keep device is placed in horizontal position, cement is compacted tightly to avoid the
device cause inclination or subsidence once tires rolling over the device.
