Sonora Series

Self – Sustainable Wireless Sensor Series

SONORA wireless autonomous sensors series is based on the LoRaWAN networking protocol. All SONORA series sensors have integrated vibration energy harvesters that utilize Viezo patent pending piezoelectric polymer technology. Stress tests conducted in third party laboratories have proven that even under the moderate vibrations the service lifetime of a product will reach the 15 years period.

Deploy & Forget Solution

Set up SONORA wireless sensors in minutes. Monitor temperature, humidity, vibration, noise changes in your application for years!

  • Lora Connectivity
  • 3x Longer Service Lifetime
  • Vibration Energy Harvesting
  • Low Power
  • Cost Savings


At Viezo we utilize Piezoelectric PVDF material to convert vibrations into energy. PolyFilm™ technology is based on the cantilever structure and as the cantilever vibrates, it generates electricity which is then stored in a supercapacitor.

Afterwards, the electricity is passed to the sensor, this way the use of batteries in Industrial IoT deployments can be avoided. We are world leaders in the power output from PVDF material. PolyFilm™ is currently patent pending

Small. Practical. Powerful.

The SONORA Series compact plastic enclosure (101x50x26mm) is specifically designed to withstand harsh environmental conditions. The device also incorporates a magnetic mount, which ensures a smooth & easy installation in any application.

Prolonged Product Lifespan = Financial Benefits

SONORA self sustainable sensors have a 3 times prolonged lifespan compared to battery powered IoT sensors. When choosing Viezo your engineers will avoid unnecessary maintenance and trips to the field, while company save on operational costs.

Sensors for your Application

The SONORA Series consists of 3 models with different sensors for your application -- noise, humidity or vibration.

Each model also has a built - in temperature sensor

AccessoriesVibration Data Logger

Since SONORA sensors heavily depend on vibration level at your application, it is quite necessary to know the vibrating patterns there before you’ll proceed further.

Terra data logger will accurately evaluate the vibrations environment at your potential application, this way your company will avoid mistakes, risks and unnecessary costs.
