Hummbox Level Piezo – Connected Piezo sensor for level monitoring

Piezo pressure sensor, connected and autonomous solution

HummBox Level Pressure is a piezo sensor, connected via Sigfox or LoraWan, self-powered, for continuous level monitoring in wells, tanks, and boreholes. Level measurement is carried out by differential pressure measurement between the liquid surface and the position of the submersible transmitter.

Applications :

  • Pressure measurement in boreholes, tanks, sanitation.

Main features :

Temperature compensated and reliable pressure measurement
Sensor for sanitation environment (option)
LPWAN communication (Sigfox ou LoRaWAN)
European design made in France

Benefits :

  • Low total cost of ownership
  • Reliable data measurement
  • Boost battery life
  • Dual mode LoRa Sigfox for more flexibility
