Press’O + – LoRaWAN


The Press’O + sensor transforms any type of 0-10V, 4-20mA analogue gauge into a Class A sensor connected to a public or private LoRaWAN® network, enabling any fluid level to be monitored, measured and remotely read.


  • LoRaWAN®, Class A
  • Easy to use and deploy
  • 1x input for pulse counting and/or status report
  • 1x analogue input0-10V
  • 1x analogue input4-20mA
  • Stabilised and switched 10V or 14V power supply, to manage the power supply of the gauge connected to the sensor
  • Differential data compression
  • Battery operated or 9-24V external power supply
  • 5-year battery life (data compression mode)
  • IP55


Application: Tank level measurement at the Renault Flins plant

Associated with various sensors:

  • Reporting at regular intervals of:
    – the water pressure, gas pressure on a water or compressed air system.
    – the pressure head in a well.
    – a pressure associated with the fill level of a tank (fuel oil, liquid fertilizer).
    – a global acceleration level, vibration detection.
    – a high temperature in an industrial process.
  • Monitoring of 13.5, 24 or 48V battery charging voltage.
  • Process monitoring: cathodic protection, beer pump.
  • Humidity detection.
