1. Functions Change Log

WSSFC-CAP10 is a Sigfox fuel level sensor that utilizes the 10-year experience of Daviteq in digital capacitance
measuring technique. It delivers high accuracy and stability with 0.1% of span. Ultra-low power design and smart
firmware allow the complete Wireless and Sensor package to run on 2 x AA battery 1.5V for 2-5 years with 15 minutes
updates. It can support the following regions RC1, RC2, & RC4.
Typical Applications: Monitoring fuel level and fuel consumption in fuel tanks of Genset, Boiler, Heavy equipment or
machinery...

5. Scope of delivery

After that, Sigfox node will send the first message to Base station.
Then during the operation, there are 03 cases of sending data to base station:
1. When the sensor sampling time interval is reached, the Sigfox node will read the data from Input or sensor
and performing the calculation. After that it will check calculated value with alarm thresholds. If the calculated
was out off the threshold values (Lo or Hi), called alarm, and the number of times of alarm did not pass the limit
of number of alarms, then it will send data to Base station immediately;
2. When the sending time interval is reached, it will send data to Base station immediately, regardless of value;
3. By using the magnet key, the Sigfox node can be triggered to send data to base station immediately. There
will be a beep sound from the buzzer meaning the data has been sent.
6. Operation Principle
Upon power on, the Sigfox node has 60 seconds to wait for off-line configuration (via cable with ModbusRTU
protocol).
NOTE:
Once sending the data to base station by this alarm event, the timer of sending time interval will be reset;

6.1 RC technical details
The RF transmit power will be automatically set as the max value as allowed by the Zone.
Sigfox Radio Configuration (RC) defines the radio parameters in which the device shall operate: Sigfox operating
frequencies, output power, spectrum access mechanism, throughput, coexistence with other radio technologies, etc.
Each radio configuration includes 4 uplink classes: 0u, 1u, 2u, and 3u.
The Sigfox network globally works within the ranges from 862 to 928 MHz. But not all RCs require such a wide range of
operation.

NOTE:
Once sending the data to base station by the magnet key, the timer of sending time interval will be reset;
The shortest time interval between the two manual triggers is 15s. if shorter than 15s, there will be no data
sending and you will not hear the beep sound.
the push button can only be used for the first 60 seconds after powering up.

* Duty cycle is 1% of the time per hour (36 seconds). For an 8 to 12 bytes payload, this means 6 messages per hour,

** Frequency hopping: The device broadcasts each message 3 times on 3 different frequencies. Maximum On time
400 ms per channel. No new emission before 20 s.
*** Listen Before Talk: Devices must verify that the Sigfox-operated 200 kHz channel is free of any signal stronger
than −80 dBm before transmitting.
Sigfox’s high limit EIRP recommendation is included in each column although regulations sometimes allow for more
radiated power than the Sigfox recommendation.
Sigfox’s recommendation is set to comply with the Sigfox technological approach of:
Low current consumption
Balanced link budget between uplink and downlink communication

6.3 Measurement principle of Sigfox Sensor

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.
Once reading the value, 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 will be sent to Sigfox base station in the payload data.
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. Please refer below the graph of alarm processing.

Using the configuration cable to connect to the sensor as below picture.
During connection with Modbus configuration tool, the Sigfox node will send all data in realtime: Battery, Battery level,
Vref, Button status, reed switch status, PCB temperature, Measured value, alarm status.
Step to configure & check data:
Step 1: Install the Modbus Configurator Software in the link below
https://filerun.daviteq.com/wl/?id=yDOjE5d6kqFlGNVVlMdFg19Aad6aw0Hs
Step 2: Plug the configuration cable to Computer via USB port;
8. Offline configuration
Serial port configuration on computer: 9600 baud, None parity, 1 stop bit.
Reading data by Function 3.
Writing data by Function 16.
NOTE:
The Modbus configuration can be done in the first 60s after power up the Sigfox node. After 60s, if user can not
finish the configuration, user need to reset the power of Sigfox node again, by removing battery in at least 15s.
How to use the Modbus configuration software

Step 3: Open the housing;
Step 4: Plug the connector to the configuration port;
Step 5: Import the configuration file by importing the csv file: Go to MENU: FILE / Import New / => select the file
with name CONFIGURATION TEMPLATE FILE FOR SIGFOX CAP10 SENSOR FW1.0.csv ( in the link below ). Then click
Connect;
CONFIGURATION TEMPLATE FILE FOR WSSFC-CAP10

To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Sigfox sensor and
Base station. In real life, there may be no LOS condition. However, the Sigfox sensor still communicate with Base
station, but the distance will be reduced significantly.
9. Installation
9.1 Locate the good place for Radio signal
ATTENTION:
DO NOT install the Sigfox sensor or its antenna inside a completed metallic box or housing, because RF signal
can not pass through metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood,
leather, concrete, cement…is acceptable.
9.2 Mounting
9.2.1 Bracket installation

Sigfox sensor connected to fuel sensor via M12 . connection cable
9.2.2 Site installation
WARNING: The sensor must be securely fixed near the measuring area.
