1.4 Installation
Lay the product flat on the table
Hang on the wall
Make sure antenna is installed before turn on the device.
When you get the device, it is off. Just press the button for 3 seconds and you can turn on the device. When you
turn on the device, there are 4 led on the top, all led will twinkle from left to right. If you turn off the device, press
the button for 3 seconds and all led will twinkle from right to left, after turn off the device, no data collecting and
uploading.
When turn on the device, normally the sensor will read data and upload every 10 mins, if you want to send data
immediately, you can just press the button for short time, less than 1 second, and sensor will read and upload
data. While press the button, 4 led will be green at the beginning, and then TX led on the device will be green
2. User Guide
2.1 Turn on/off the device
2.2 Data uploading by press the button
while sending data as below:
as below. POWER is the battery level, normally when you turn on the device, 4 led lights will be green which
means the battery level is 100%. If only 3 led are green which means the battery is 75% left. There is low battery
alert and POWER will be red while low battery level.
TX and RX means sensor is sending or receiving data.
Sensor is green means sensor is reading and uploading data, if sensor is red, that means sensor is not working,
please kindly check if the sensor is will connected.
There is one USB-C port as below, which is for power on and config, connect device to laptop with a USB-C cable,
and you can config the device, make sure to install USB driver and here is the link for driver: Serial Port Driver
When turn on the device, it will send data immediately, also you can press the button for 1 seconds, then the
device will also send data. Normally when you get the device from factory, the reset time for data sending is
every 10 mins, and if you want to change the time, you can connect the device to computer for config, here there
is instruction about the time configuration.SensorTool Manual.
2.3 Led display on the device 4 led on top of the device, and they are POWER/TX/RX
and SENSOR from left to right
2.4 USB-C Port
3. Data Uploading
SL200 water leak sensor is based on standard LoRaWAN Class A, so you can connect to any LoRaWAN network
through OTAA.
On the back of device, you can find information as below, with this information, you can connect to any
LoRaWAN server.
4. Connect to LoRaWAN Network
Here below take TTN as an example about how to connect the device to TTN server:

information as below:
5. Wireless LoraWAN Sensor Data Format
Picture as below, FRMPayload is sensor data.
Type Value Value Value
1 Byte 3 bit 5bit 1 Byte
0x00 Version Battery Level Reserve
Type
1 Byte
Value
1 Byte Comment
0x09 switch state
1-byte unsinged integer. The
sepecific meaning depends on
the item.
Gennerally, a single bit represents
one channel of switching value(0
is OFF or 1 is ON)，and 8 switch
value Max
For Example:
FRMPayload(hexadecimal string) is 00 3F 24 09 00
0x00 is device information
0x3F (binary is 0011 1111b) version 1 and level 31
0x24 is reserve, generally is MCU voltage
0x09 is water leak sensor
0x00 is no water, 0x01 is there is water

Note: Factory reset data uploading is every 10 mins, customers can change data uploading frequency as below:
Connect sensor with a USB-C cable to computer for local configuration, through local configuration, you can
change the packet frequency. Refer SensorTool Manual.
