WATTECO - INTENS'O LoRaWan energy meter

The INTENS’O sensor measures the electrical current that flows through the AC power supply of any equipment. The sensor is used to determine the equipment status according to one or more configurable current thresholds. Data is transmitted over a public or private LoRaWAN® radio network.

INTENS'O analyses the current of any electrical conductor. The current magnitude is measured using a current transformer without disrupting the current path.

INTENS'O regularly measures the current and periodically transmits the operating status of the equipment. When the current is crossing a threshold previously set by the user, the sensor automatically transmits an alert with the associated current measurement. The alert can be transmitted over a public or private LoRaWAN®communication network.

INTENS'O is quickly and easily placed on the power phase conductor of any control cabinet or on the electrical motor of a piece of equipment for instance. It is used to check:

- if the equipment is operating or down, due to a mechanical failure for instance;
- whether a street light is operating properly or not in order to quickly replace the street lamp.

Up to 7 different current thresholds can be set by the user. When used in a building or in a factory for instance, It can be used to set up a predictive maintenance service.

INTENS'O is easy to use, deploy and maintain. The sensor is equipped with:

- a current transformer
- a 3m cable allowing the current clamp to be placed on the live conductor in the electrical panel, close to the motor. The sensor can be remotely located within the optimum radio coverage area,
- a 3M Dual Lock adhesive and adaptable hitching system
- an NFC identification tag (product code, serial number, batch number)
- a magnetic switch and a buzzer that allow the installer to easily enable / disable the sensor.

The sensor is powered by a 3.6V lithium battery. The autonomy exceeds 10 years when measuring current magnitude every 1 minute and when transmitting data every hour
