This is a wireless sensor that measures water level using radar technology. The combination of a high-tech radar level
sensor combined with a wireless sensor using Texas Instrument's advanced Sub-GHz technology enables long-range
transmission with extremely low energy consumption. It will connect 2-way wireless with WS433-CL wireless co-
ordinator to send data and receive configuration. It can be configured with operational parameters such as data
delivery interval, health check cycles ... remotely from the Globiots platform or via the ModbusRTU software (via
WS433-CL). Its default data rate is 50 kbps, which can be converted to 625 bps for increased communication range.
The sensor can operate for up to 10 years with just one AA battery. Sensors can be used to measure water or liquid
levels as well as for measurement in areas such as river level monitoring, chemicals, municipal water supply and
drainage, etc.

4. Operation Principle
4.1 WS433 Wireless Transmitter
When the sensor sampling time interval is reached, for example 2 minutes, the node will wake up and switch ON

For example: the measurement time is 200mS, after this time, the node will read the value of sensor using I2C, node
will switch OFF power supply to external sensor to save energy.
Once reading the sensor value, the raw data is X, it can be scaled to any engineering value by the following formula:
Y = aX + b
Where
X: the raw value from sensor
Y: the calculated value for parameter 1's value or parameter 2's value
a: constant (default value is 1)
b: constant (default value is 0)
So, if there is no user setting for a and b ==> Y = X
The Y value will be compared with Lo and Hi threshold.

After inserting the battery for the sensor, power on the co-ordinator and bring the co-ordinator closer to the sensor to
add the sensor automatically.
the power supply to supply the energy to external sensor to start the measurement. Depends on the type and
characteristic of external sensor, the sensor will take a certain time to finish the measurement.
4.1.1 Add sensor to co-ordinator

Step 1: After supplying power the Co-ordinator via M12 connector, the Node ID must be registered within the first 5
minutes, up to 40 WS.
Step 2: Bring the wireless sensor closer to the Co-ordinator's antenna then take off the wireless sensor battery, wait
for 5s then insert the battery again. If:
Buzzer plays 1 peep sound, LED blink 1 time, that means registering Node ID on Co-ordinator successfully.
Buzzer plays 2 peep sounds, LED blink 2 times, that this Node ID is already registered.
Node id added in this way will be written to the smallest node_id_n address which is = 0.
Set Rssi_threshold (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL), default -25): The case if Co-
ordinator is on high position and need to add node sensor. We set the sensor as close as possible and set the
Rssi_threshold to -80, -90 or -100 to increase the sensitivity to allow WS433-CL-04 can add sensors at a longer
distance. After that, perform 2 steps of adding sensors and then reset Rssi_threshold = -25.
Enb_auto_add_sensors configuration (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL)): In case
you do not want to turn off the power WS433-CL, you can set Enb_auto_add_sensors = 1, this way we have 5
minutes to add nodes (add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0.

for-long-range-wireless-co-ordinator-ws433-cl
Open the cover of sensor then use the push button to set the data transfer speed for the first 30 seconds when the
battery is first installed, after 30 seconds the push button function does not work.
Press and hold the button for 2 seconds => LED blinks once => Release the button to set Data rate RF 50kbps
If you do not hear the "Peep" sound, please disconnect the power the co-ordinator, wait a few minute and try
again.

4.1.2 Add sensor node into WS433-CL-04 (1) through intermediate
WS433-CL-04 (2) and Modbus
In case the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the
sensor cannot be brought close to WS433-CL-04 (1). For more details:
4.1.3 Button Function

Press and hold the button for 5 seconds => LED blinks twice => Release the button to set Data rate RF 625bps
Press and hold the button for 10 seconds => LED blinks 3 times => Release the button to reset RF parameters
(frequency, RF output power, data rate), if held for more than 30 seconds then the button function does not
work.
First, you need to prepare
Reset default WS433:
Frequency: 433.92 MHz
RF transmit power: 15 dBm
RF data rate: 50 kbps
4.1.4 Configure sensor parameters in Co-ordinator
Num of Node will indicate the number of nodes managed by WS433-CL.
Every time a node is added, the Num of Node will increase by 1.
Every time a node is deleted, the Num of Node is reduced by 1.
Writing Num of Node = 0 will delete all 40 node ids to 0.
If you want to delete a node id, then write it = 0 with the Write function is 16 and the Read function is 3.
Step 1: Connect Antenna, RS485 - configuration cable and power supply co-
ordinator

You can download Daviteq Modbus Configuration Tool with the following link:
https://filerun.daviteq.com/wl/?id=bU88UgTMDNPIXjafxwxQeU89JtAoXEZR
Unzip file and run file application "Daviteq Modbus Configuration Tool Version 1.1"
Step 2: Open Modbus tool on PC
Template File: https://filerun.daviteq.com/wl/?id=hgrjOg3wwvyrvAZ54p8iZiFpDyXTcnec
How to use the Modbus configuration software

Choose COM Port (the Port which is USB cable plugged in)
Set the BaudRate: 9600, Parity: none
Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the WS433-CL-04 is
being connected with computer;
Next, we need to import the configuration file for WS433-CL-04 by importing the csv file: Go to MENU: FILE /
Import New / => select the template file.
Use Modbus tool to check added sensors and configure sensor operating parameters.
In the memmap file, refer to the Memmap of WS433-AI sheet to configure the sensor's operating parameters
accordingly.
Step 3: Configure the sensor's operating parameters.

The Radar Level Transmitter antenna emits narrower micro wave pulses which will be transmitted via the antenna. The
micro wave will be reflected back after touching the surface of a medium, then antenna system will receive it and
transmit it into the electrical circuit, which will be automatically turned into the level signals.
A: Setting measuring range
B: Low level adjustment
C: High level adjustment
D: Dead zone
Measuring reference: the bottom surface of threads or the sealing surface of a flange.
4.2 Radar Sensor RD-2695S
Note:
When using the radar level transmitter, must keep the highest level of medium out of the dead zone
(see area D shown in the drawing)

To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Wireless sensor and
Gateway. In real life, there may be no LOS condition. However, the Wireless sensor still communicates with Gateway,
but the distance will be reduced significantly.
