1 Overview
These documents are helpful to understand the DO200 Parking Occupation Sensor’s
following:
▪Function of Device
▪How to install SIM card?
▪Protocol and API
▪Hardware Interface(debug/configure interface and battery interface )
▪Modify equipment parameters ( upload interval and APN,IP ....)
▪FAQ
2 Device Function DO200_NB-IoT Parking Occupation
Sensor's
Function:The device can detect if the parking space is occupied. When the vehicle is
detected to enter or leave, the sensor will be triggered to report the data.
When the device is restarted and the device is restarted, the sensor will learn the
surrounding environment, so it is considered to be a car-free state at this time.
3 How to install NB-IoT SIM card?
NB-IoT Sim card:MICRO card,;the frequency band of the SIM card used needs to be
the same as the device frequency band.
Insert NB card: sensor use self-elastic card slot, please find the card slot and insert
the NB card(If you want to change or remove the card, please press the card and it
will pop up automatically.).
Please pay attention to the installation direction of the card, as shown below:

4 How to restart sensor through magnet?
Magnet:
Move the magnet around the probe one turn and remove the magnet. This process
restarts the device. If the device is successfully rebooted, the device will report a
data that is displayed as being moved and the current full/empty state.
5 Device interface definition

6.3 Configure device parameters (upload time, APN etc.)
After completing the two steps 6.1 and 6.2, you can refer to this step to configure
the corresponding parameters through the serial port software.
1 serial port software parameter setting
Open the serial port software. The default serial port information is shown in Figure
6.6.
The parameters required for the DO200 serial port are shown in Figure 6.7;
Port number ( you can select port Number from device manager of your system)
Set the baud rate: 115200

2 Connect the device's power(battery)
Connect the capacity and battery to the connector location on the motherboard as
shown in Figure 6.8:
Figure6.8 Connect the battery
3 Send command
When the battery is connected, you can see some information output from the serial
port. At this point, the device starts working and can send commands. At this time,
the corresponding parameters can be configured to configure the required
parameters.
Note: when the serial show “sleep”,mean that the sensor have come into sleep mode
Sending instructions at this time is invalid.so you need to restart the sensor by
magnet.
For example 1: change upload time to 10 hours
The command is: 8888010A, as shown in figure6.9,
