1. Introduction
1.1 What is LDS01 LoRaWAN Door Sensor
The Dragino LDS01 is a LoRaWAN Door Sensor. It detects door open/close status and uplink to
LoRaWAN network. The LDS01 is small sensor; the dimension is as small as 64 x 30 x 14 mm.
LDS01 is powered by a CR2032 coin battery, in a good LoRaWAN Network Coverage case, it can
transmit as many as 12,000 uplink packets (base on SF7, 14dB). in poor LoRaWAN network
coverage, it can transmit ~ 1,300 uplink packets (base on SF10, 18dB). The design goal for one
battery is up to 1 year. User can easily change the CR2032 battery for reuse.
The LDS01 will send periodically data every day as well as for each door open/close action. It also
count the door open times and calculate last door open duration.
Each LDS01 is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys
to local LoRaWAN server and it will auto connect after power on.

2. Power ON LDS01
When receive the LDS01, please open the enclosure and remove the isolated paper and PRESS
RESET so the coin battery can power on the device and device runs on low power mode. The LED
will blink when devices is powered.

4. Operation Mode
4.1 How it works?
The LDS01 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join
network. To connect a local LoRaWAN network, user just need to input the OTAA keys in the
network server and power on the LDS01. It will auto join the network via OTAA.
In case user can’t set the OTAA keys in the network server and has to use the existing keys from
server. User can use AT Command to set the keys in the devices.
4.2 Example to join LoRaWAN network
Here shows an example for how to join the TTN Network. Below is the network structure, we use
our LG308 as LoRaWAN gateway here.
The LDS01 in installed on the door edge to detect the open / close event. And send the status to
LoRaWAN server. The LDS01 will uplink two type of messages to the server.
A keep-alive message which send once per day.
A door event message when there is a door open/close.
The LG308 is already set to connect to TTN network . So what we need to now is only configure
the TTN:
Step 1: Create a device in TTN with the OTAA keys from LDS01.
Each LDS01 is shipped with a sticker with unique device EUI:

User can enter this key in their LoRaWAN Server portal. Below is TTN screen shot:
Add APP EUI in the application.
Add APP KEY and DEV EUI
Step 2: Power on LDS01 and it will auto join to the TTN network. After join success, it will start to
upload message to TTN and user can see in the panel.

If the payload=0100003C, means to control the LDS01’s Keep Alive interval to 0x00003C=60(S)
Type Code 0x04
If payload = 0x04FF, it will reset the LDS01.
Type Code 0xA6
Example: 0xA601: Clear Counting
For LDS01: reset both count number and time.
4.5 Integrate with Mydevice
Mydevices provides a human friendly interface to show the sensor data, once we have data
in TTN, we can use Mydevices to connect to TTN and see the data in Mydevices. Below are
the steps:
Step 1: Be sure that your device is programmed and properly connected to the network at
this time.
Step 2: To configure the Application to forward data to Mydevices you will need to add
integration. To add the Mydevices integration, perform the following steps:
