Industrial parks

On road parking space
Commercial parking slot

Other public parking slot

Note: The strong magnetic field or the field where magnetic varies greatly are not suitable for the detector use.

5 Product Specifications

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

Please try to install the device on the daytime and finish the installation as soon as possible.
Please pay attention to road safety and wear reflective clothes for safety.
Installation Tool Preparation:
Ruler: Measure the installation position
Marking pen: mark the installation position Coring bit
Blower: blow away the powder
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

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.

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.

Step 5: Click “Register end device” on the bottom of page.

9.2 Activate the Device

Step 1: Turn on phone’s Bluetooth function

Step 2: Open the configuration app “Moko Parking Sensor Configure Tools” and come into detector tool interface

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.

10 Maintenance Instruction

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.
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.

When the server sends calibration command to device, make sure there are no vehicle in the parking space, otherwise calibration will make error.
When the device works abnormally, the device can be reset through LoRaWAN downlink command.
If device cannot connect by blue-tooth, please try to change a magnetic stripe.

Re-calibration is needed once the device is moved during detecting.
