KADO UNIO – IoT sensor of electrical signals

The KADO UNIO sensor is designed to monitor and measure electrical signals at the input terminals of the device. It is used for monitoring of external industrial sensors or end-switches. Its use is appropriate wherever there is no option to monitor these signals in a standard way. Emphasis is on long battery life and low data transmission costs.

The KADO UNIO sensor is the first of its kind with regard to the power supply application of external sensors. In practice, this means that you can connect not just any external sensor to the sensor, but you can even control its switching period. Combined with the Sigfox wireless technology, the KADO UNIO is an universal IoT device with countless applications not only in industry.

The most frequently connected external sensors are:

  • Pressure gauges
  • Hygrometers
  • Thermometers
  • Flowmeters
  • Level meters
  • Power sensors

And many others. An important criterion is that the external sensor has an output of 0 - 10 V or or 4 - 20 mA.

The KADO UNIO sensor further monitors states of the following signals at present time intervals:

  • 1x current input 4 - 20 mA
  • 1x analog voltage input 0 - 10 V
  • 4x digital voltage input 0 - 10 V (end switch)

In the case of digital input, the sensor can be set to send a message every time a digital input state is changed. The KADO UNIO sensor can additionally be equipped with a GPS signal sensor and an accelerometer. In addition to reporting the current position, the sensor can detect motion initiation, continuous motion and stop motion.

The KADO UNIO sensor has a durable and weather-proof design and can be easily mounted at the place of use. Its battery lasts up to 10 years (depending on the number of measurements and transmmitted messages) without any battery replacement and it can be used literally wherever you need it. The KADO UNIO sensor can be placed in indoor, outdoor or offsite.

Why you should use the KADO UNIO sensor?

  • Are you looking for a versatile solution for your project?

  • Are you interested in remote energy readings with online access to data?

  • Do you need to know the position of the end-switch or to find a simple event counter?

  • Innovative technologies are exactly what your busine`ss needs?

Principle of communication

The KADO UNIO sensor communicates over dynamically evolving radio network Sigfox for IoT (Internet of Things) with a frequency band of 868.13 MHz. Sigfox allows bi-directional communication of sensors with a limited number of feedback messages. Thanks to Europe-wide coverage, it is possible to communicate and control all sensors especially on a long distances cheaply, safely and with a low power consumption.

The data from the sensor is sent via the Sigfox radio network to the PHARIS IoT Cloud where the data is processed and prepared for view.

PHARIS IoT can also send data to customer’s platform or the KADO UNIO sensor can be provide as a pure HW with Sigfox ID and PAC.


The KADO UNIO sensor passed all the requirements and tests in accordance with Sigfox ReadyTM certification process and receiving Class 0 level. It means that the sensor emits the highest allowed energy through its antenna to allow communication over very long distances with very low energy consumption.

Mounting and putting into operation

The sensor should be located in such a way that it is protected from vandalism or unintentional damage during operation, and it should be possible to receive GPS signals (unshielded space), if the sensor is equipped with GPS.

Sensor mounting is possible in three ways:

  • Using neodymium magnets (magnetic pull force is about 400 N)
  • Using a 4x M4 screwdriver
  • Using a double-sided tape

Sensor activation is done by approaching the magnet to the reed switch inside the device. In the same way, there is also possibility of the sensor deactivation at planned shutdowns.

The period of measurement and message transmission over the Sigfox network is configurable parameter.
