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.
LW009-SM

And select “Manually” on register interface.
Then select the corresponding frequency band, choose ABP mode on activation mode and the
LoRaWAN version is V1.0.3.
Note: If you use EU868, pls select Europe 863-870 MHz (SF12 for RX2).
Step 4: According to the information obtained from Step1, fill in the corresponding LoRaWAN
access parameters.

11 www.mokosmart.com
Step3: Place the magnet stripe (Put together with mounting screws in the box with the device) in
the groove at the top of the device and stay for 1~5seconds, then move away and click
“Connected Device” of configuration app at the same time.
Step 4: After Click “Connected Device”. If connect successfully, the device’s basic information will
be displayed in APP interface.
Step 5: Select “Auto Install”, the device will wake up and do the calibration automatically, the
system time will be synchronized. The device mode will be Normal Mode.
Note:make sure there are no vehicle and other metal material
within1 meter around the device or calibration will make error before
“Auto Install”.
Note: The device can be calibrated again by click “Auto Install” again.

10 Maintenance Instruction
1. Battery life: The battery life refers to the service life under normal conditions. When the device
is used in poor LoRa network (SNR≤-12), the device function will be affected and the battery life
will be shortened.
Note: Normal conditions means that the device can work normally most of the time and the
wireless communication is stable.
2. Make sure that there are no vehicle and other metal material within 1 meter around the device
during the calibration process, otherwise calibration will make error.
3. When the server sends calibration command to device, make sure there are no vehicle in the
parking space, otherwise calibration will make error.
4. When the device works abnormally, the device can be reset through LoRaWAN downlink
command.
5. If device cannot connect by blue-tooth, please try to change a magnetic stripe.
6. Re-calibration is needed once the device is moved during detecting.
