Ventilation sensor

The VENTILATION sensor from nke Watteco is an easy-to-use wireless sensor operating from any wireless network using the SIGFOXTM protocol.

The sensor is typically installed on the buildings roof, sufficiently close but higher than the ventilation chamber. It should be protected from direct sunlight and rain. A plastic air tube (internal diameter: 6mm) is connected to the ventilation chamber and the sensor.

The wireless sensor has the following alarm capabilities:

• ON/OFF
• Low battery voltage
• Min & Max air de-pressure
• Min & Max temperature from embedded or remote NTC probe (optional)

The unit has the optional capability to report every 24 hours the average, minimum, maximum temperature measured that is useful to compute unified degree days which is a typical indicator of energy consumption and costs for heating or cooling. In this mode, the average pressure over 24 hours is also transmitted.

The VENTILATION sensor is easy to use, deploy and maintain:

• NFC tag for identification (Part number, serial number and manufacturing number)
• Magnetic switch to activate/de-activate the sensor

Powered through a 3.6V/3600mAh Lithium battery, it allows an autonomy up to 12 years when measuring pressure 1 times per hour and transmitting data one time per day.

The configuration of the transmitter can be done at factory or on-site allowing the choice of measurement cycle, measurement frame radio-transmission periodicity, alarms threshold values.
