The outdoor Gas VMC sensor measures the vacuum established by outdoor ventilation chambers. The sensor regularly transmits its data over the ultra narrow band, long range, low power, secure SigFox™ radio network. It also detects the on/off position of equipment. The SIGFOX® GAS & SANITARY VMC sensor is a battery-powered, on-board system that monitors centralized ventilation boxes by periodically measuring the vacuum. The data transmission on the SIGFOX® network is done periodically (configurable): - Calculated average of measured depressions, - Minimum and maximum vacuum measured, - Battery voltage level - Trigger pressure switch (if optional) Powered by a battery, the autonomy of the sensor is more than 8 years for a configuration with one vacuum measurement per hour and one transmission per day. The sensor is installed outdoors near the housing. It must be fixed under cover (in a Plexo case for example) so as not to be subject to too quick temperature variations (sunlight, rainfall, etc.) which can affect the quality of the measurement. The Sensor must be kept away from any metal parts that could strongly attenuate the radio frequency transmission (the Sensor must be placed more than 0.5 meter from the Housing for example). Characteristics SigFox™ technology Easy to install and use Autonomy > 8 years Measurements in the VMC air flow: – Depression: 0 to + 500 Pa; -/+ 10 Pa – Temperature: 0°C to 50°C; -/+ 1°C  IP65 Optional input for mechanical depressostat Applications: Supervision of gas and sanitary ventilation systems. Energy optimisation in buildings (residential, tertiary).
