Operating Environment
Requirement
No ferromagnetic materials, No strong magnetic
field nearby;
No metal shield covers the detector
Note: Typical scenario means the device report information every 12 hours, there are 5 times for
vehicles come in and go out to a parking space a day.
6 Product Appearance
7 Working Principle
The frame and shell of a car are made of ferromagnetic material (various types of steel), which will
make disturbance to surrounding magnetic field. According to this characteristic, LW009-SM
determines whether there is a car in the parking space.
With build-in dual-sensors (geomagnetic sensor and microwave radar sensor), powerful signal
analysis and processing algorithm. The product can work out redundant enhanced information,
especially acquire complementary and optimization to the reverse sensitivity characteristic s of
chassis with different height.
Compared to traditional parking sensor with single sensor, LW009-SM greatly improved the
detection accuracy and reduced information loss.
8 Installation Guide
8.1 Installation Preparation

LW009-SM
6www.mokosmart.com
1.Please try to install the device on the daytime and finish the installation as soon as possible.
2.Please pay attention to road safety and wear reflective clothes for safety.
3.Installation Tool Preparation:
Ruler: Measure the installation position
Marking pen: mark the installation position
Coring bit
Blower: blow away the powder
4. Product installation orientation requirements
The direction of the arrow above the device should be at 90 degrees angle to the front of the
vehicle, as shown in following figure, both mounting directions are recommended. Geomagnetic
The detector must be installed in the required direction, otherwise there may be a possibility of
false alarms.
8.2 Installation Steps
Step 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 parameters which used to device
registration) is clear.
Step 2: Drill Hole

LW009-SM
7www.mokosmart.com
Find and mark the center of the desired detector location.
Drill four holes (Depth: around 60 mm; Diameter: around 8 mm) into the road.
Step 3: Install Expansion Bolts
Install the four expansion bolts separately to the device.
Step 4: Place the Device
Place the LW009-SM face up with the 4 expansion bolts aligned with the 4 mounting holes in
Figure 3. Press the 4 expansion bolts into these 4 mounting holes so that the bottom surface of
the LW009-SM is tight against the road surface and there is no gap between the underside of the
bolt cap and the device, then lock the bolts with an Allen screwdriver.

9 Quick Start Guide
To facilitate the configuration and use of the LW009-SM, the product can be configured and
calibrated using the corresponding configuration APP (Moko will provide APK of configuration
APP).
Note: After the successful installation of the APP, the APP will request some mobile phone
permissions, such as Bluetooth access permissions. Please click "OK", otherwise the APP will not
work well.
9.1 Register the Device on Network Server
The TTN server is used here as an example
Step 1: The LoRaWAN mode of LW009-SM is OTAA mode in default. MOKO will provide the
LoRaWAN access parameters, which includes DEVEUI, DEVADDR, AppSkey and NwkSKey.
Stpe2: Open TTN page, then register the applications
Step 3: Click “Add end device” on application page.
