Key features highlights :


The sensor transmits more than just filling levels. GPS data from the sensor allows assets such as containers to be tracked, while other information such as temperature readings ​​and battery charge status enable to benefit from predictive maintenance capabilities.

Two different sensor configurations are available:

A WILSEN.sonic.level UCC2500 model for distances up to 2,5m through a wireless ultrasonic sensor.

WILSEN.sonic.level UCC4000 model for distances up to 4m through a wireless ultrasonic sensor.

Industrial Use

Its suitability for industrial use sets the WILSEN.sonic.level apart from other IoT sensors—it has a rugged housing with IP66/67 protection and can also be used outdoors at temperatures of -25 °C … +70 °C.

Comprehensive measurement data acquisition

  • Ultrasonic sensor for level measurement
  • Geolocation via GPS
  • Temperature values and
    battery status


Description :

The WILSEN.sonic.level LoRaWAN, battery-operated and wireless level sensor is used primarily in smart city, logistics, farming, and environment sectors. The sensor parameters allow it to be adjusted for a diverse range of installation conditions and for detecting different materials.

Fill levels are measured at regular intervals and transmitted to operational experts internet-based applications. The measurement and transmission frequency are parameterized via a mobile application and Bluetooth interface.
