Manual for Sigfox-Ready AC
Current Sensor - WSSFC-AC | FW1
1. Quick Guide
Reading time: 10 minutes
Finish this part so you can understand and put the sensor in operation with the default configuration from the
factory.
1.1 What is the Sigfox-Ready AC Current Sensor and its
principle of operation?

WSSFC-AC is a Sigfox-Ready sensor with an integrated AC current measuring transducer that can measure the AC
current from a current transformer with max 5A AC current. It is compatible with any brand of current transformer (CT)
on the market which gives an output max of 5A AC. The CT ratio will be selected based on the load current.
It is battery-operated and able to connect to any Sigfox network in the World. It supports all frequency zones such as
RC1, RC2, RC3c, RC4, RC5, RC6, and RC7.
For the principle operation of the AC current sensor, please refer to this link.
Please refer to this link for typical applications.
The device will send uplink messages in the following cases:
Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell
the user the HW version, FW version, and current configuration of the device;
Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called
CYCLIC_DATA. The payload will tell the user the following data like measured value (AC current value), battery
level, alarm status...
Case 3: In case the Alarm function was enabled (in the configuration of the sensor), if the measured value
passed the threshold, it will send the uplink message immediately. This message is called ALARM. The payload
also tells the user the data like measured value (AC current value), battery level, alarm status...
Case 4: The HEART_BEAT uplink message will be sent once a day (the default setting, can be changed in
configuration) to allow the Sigfox back-end system can send the downlink message for changing the
configuration of the sensor. Please refer to the downlink section for more details. The uplink payload will tell the
user the HW version, FW version, and current configuration of the device;
Case 5: During commissioning, testing, or calibration sensor, the user can force the device to send the uplink
message so that they can get the data immediately. This message is called FORCE_DATA. The payload will
provide data like raw measured value, scaled measured value, battery level, alarm status... It can be forced by
applying the magnet key on the reed switch in 1s;
Case 6: In case users want to change the configuration immediately, they don't need to wait up to 1 day for the
HEART_BEAT message, instead they can force the device to send a special uplink message so that the device can
get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by
applying the magnet key in more than 5s.
The sensor was pre-configured at the factory with default values for configuration parameters that meet the most use
cases. However, depending on the specific use case, the customer can adjust those parameters. Please refer to
section 3.2 for more details.
The sensor is powered by 2 x AA 1.5V batteries for many years of operation. We do recommend using Energizer L91
battery which is very popular and high performance. This battery has a capacity of up to 3500mAh with a working
temperature range from -40 to +60 oC. The instruction for installing the batteries is in this link.
For Battery life estimation, please refer to this link.

calibration.
The Daviteq Sigfox-Ready AC current sensor comprises 02 parts connected together as shown below picture.
- The Daviteq Sigfox-Ready wireless transmitter;
- The Daviteq AC 5A current Transducer;
The AC current transducer is to measure the actual AC current of the secondary winding of the CT.
The Sigfox-Ready is to read the AC current value from the transducer and perform the scaling (A and B values, during
calibration). The scaled current will be multiplied by the CT ratio to deliver the final value which is the actual load
current that the user wants to measure.
Scaled_CT_Current = A x CT_Current + B
Actual_Load_Current = Scaled_CT_Current x CT
Where:
A : Constant A
B : Constant B
CT_current: the measured current from the transducer (Secondary winding current of the CT)
3. Advanced Guide
3.1 Operating principle of the Sigfox-Ready AC current sensor
3.1.1 Operating principle of the complete device
For example: the CT_current = 1.5A, the CT ratio = 20 (the CT is 100/5), A=1, B=0 ==> then the
Actual_Load_Current = 1.5 x 20 = 30A
Note: the Low cut value of Actual_Load_Current is 0.5A. That meant the device can not measure the current
load less than 0.5A

To understand how the AC current transducer can measure AC current, please refer to this link for a complete
understanding of this measuring technique.
Below are some important configuration parameters which affect the operation of the device like battery life,
measurement accuracy, and alert threshold.
For Battery life estimation, please refer to this link.
measure_period | Default = 600s
This is the time period for the wireless transmitter to wake up and take the measurement from the transducer.
The default value is 600s. Users can reduce this value, but smaller value, shorter battery life!
cyclic_data_period | Default = 600s
Interval time to send an uplink message regardless of any conditions
sensor_boot_time | Default = 1000mS
This value will affect the measurement accuracy. DO NOT change this value!
Those configuration parameters can be changed by downlink or offline tools. For more other configuration parameters,
please refer to the next section.
Sensor configuration can be configured in 02 methods:
Method 1: Configuring via Downlink message. Please find the instructions in this link, but please take note of
the FW version of the Document.
