LoRaWAN Indoor Air Quality Sensor

The Vaqa’O sensor measures the temperature, relative humidity, concentration of volatile organic compounds (VOC) and carbon dioxide (CO2) in the ambient air of a room in a building, an apartment or a house. It allows Indoor Air Quality (IAQ) monitoring.

The data is transmitted via a public or private LoRaWAN™ radiofrequency network.

Features:

• LoRaWAN™, Class A
• Easy to install and use
• > 3 years of autonomy
• Measurement range / Accuracy:
  – Temperature: +0°C to +55°C / ± 0.2°C
  – Humidity 0% to 100%rH / ± 2%
  – CO2: 0 to 5000ppm/ ± 100ppm
  – VOC index: 0 to 500 / ± 5
• Indicators (LEDs): Network and IAQ association

 The VAQA’O sensor measures temperature, humidity, CO2 and VOC concentration in the building environment. The transmission of data on public or private LoRaWAN® network is done periodically or in case of alert of exceeding thresholds: 

• Min. and max. temperature 
• Min. and max. humidity 
• CO2 min. and max. 
• VOCs min. and max.

If the sensor is unclipped from its wall mounting or moved, an alert is transmitted. Installation and commissioning is quick and easy. The sensor is equipped with : 

a switch (ILS) allowing association to the network and various interventions (e.g. prolonged standby), 

LEDs located in the air vents to monitor the association of the sensor with the network and the main status of the sensor during commissioning. 

Once the connection with the network is established, the LEDs indicate the Indoor Air Quality (CO2 and VOC). To save batteries, it is possible to deactivate the LED display of IAQ thresholds by sending a downlink, saving about half a year of autonomy. Measurement data is transmitted individually or aggregated and compressed (batch mode) before being transmitted on the LoRaWAN® network. This transfer technique considerably reduces the amount of data transmitted while preserving the autonomy of the sensor. Powered by a pack of 3 Lithium 3.6V/2600mAh batteries, the sensor’s autonomy is more than 3 years with the default configuration: one measurement on all sensors every 10 minutes and 1 transmission every hour, the data being compressed. The battery level can be monitored regularly from a distance.
