LoRaWAN™

What do I need for the device to work?

For the devices to work you will need a Gateway, access to a LoRaWAN network server (i.e. TheThingsNetwork) and application server (i.e. Thingsboard). The Gateway that SEZO prefers is the Sentrius RF1xx LoRaWAN Gateway from Laird. Upon ordering, it is possible to order the Gateway through SEZO and have it shipped together with SEZO sensors. In a package you can also request service from SEZO engineers that will help you with the whole process of setting up a network server and customizing the ThingsBoard platform.

Depending on the location, it is also possible to outsource our technician to install the devices and the Gateway for you. For a quote, please contact our sales department at info@sezo.pl

For the AC powered devices we provide the adapter with the EU plug. 

How do I know that the server has successfully received the data sent by my SEZO device?

The server received the data once you see the data with the timestamp displayed in the Network Server console/interface. If you don’t know if you are receiving data correctly or if you have any other technical issues, our aftersales department will help you with any issues through email or call.

How do I configure my gateway in such a way that it forwards the packets from the SEZO device to the destination server?

It should be configured (IP address and port) to be a network server compliant to LoRaWAN.

 

What do I get in a package?

AC-powered devices:

➡️  device

➡️  power supply

➡️  user manual and

➡️  test report in electronic form (printed upon request before shipment)

Battery-powered devices:

➡️  device  

➡️  user manual 

➡️  test report in electronic form (printed upon request before shipment)

(For battery powered devices) Is the battery included with the device?

Yes. In the SEZO CL, SEZO SL, SEZO BL and SEZO WL the battery is replaceable. We use standard Li-SOCl2 industrial batteries.

Can the devices be customized to measure parameters in a different configuration?

Yes, for large orders we can modify the devices so that they only have sensors that are needed for specific projects.

Minimum order quantity needs to be discussed with us each time as the complexity of the  customization of the device varies depending on the case. Please contact us for more information at info@sezo.pl

Which devices are designed to be used outdoors?

SEZO A1L, SEZO EL, SEZO TM. What makes them stand out in harsh outdoors conditions is a IP55 casing made out of durable polycarbonate. The casing of the devices allows for years of undisturbed functioning once the device is set in its place of destination. 

The standard warranty is 12 months, counting from the delivery.

 

Which device has the most sophisticated sensors in it?

➡️  SEZO A1L ⬅️ 

It measures temperature, humidity, air pressure, luminosity, noise, Particulate Matter levels as well as acceleration, magnetic field and can detect motion (PIR).

How does the SEZO WL - water leakage sensor - detect water leakages?

The device has four detection channels for outgoing sensing strips. It detects water and sends alerts when the liquid contacts the sensing strips.

 

The device has four sensor strips, making it possible to detect leaks in four different zones. The device, once the strips detect water, sends an alert informing in which zone a leakage has been detected.

I can't perform the configuration. In which switch position should the configuration be made?

The configuration should be made on the “run” position. “Prog” position is reserved for the firmware updates.

For more information please go to page 6 of the User Manual that was attached with the product.  If you still have technical issues, our aftersales department will help you with any issues through email or a call. 

 

Are there extra drivers needed for the configuration of the device?

No, there are no extra drivers needed. After connecting, the device should appear as a “USB disk“.

See page 7 of the User Manual attached with the product.

Can the data transmission interval be modified?

Yes, it is possible to manually modify the send interval through in-build USB port.

We recommend to use an interval as long as possible to avoid packet collisions with other devices.

There is a default duty cycle control activated to be compliant with ETSI standards. Default configuration is 15 minutes. See User Manual sent along with the device.

How long does the battery last?

Approximately 22 hours. It’s a rechargeable, non-replaceable battery. It can be charged using a wireless Qi charger.

How long does the wireless charging take?

Approximately 4 hours.  The device can be charged using a wireless Qi charger.

Please note: The charger is not included in the price but it can be ordered through SEZO.  

Is the charger included in the price?

No. It is possible to order the charger along with the devices through SEZO.

Is the device waterproof?

The device’s case has an IP67 rating which means that the unit can be used in harsh outdoor environments. The standard warranty for the devices is 12 months from delivery. 

Does the location function work indoors?

The location based on GPS only works outdoors but the device records the last available location and also can send the information about the altitude of the device while the device is located indoors.

Thanks to defining the altitude we can define which floor is the device located on.

Can the sending interval be modified?

Yes, it is possible to manually modify the send interval directly through a data displaying platform. For details see User Manual sent along with the device.
