The AirBase CanarIT™ is a multi-sensor air quality monitoring device, designed for affordable network sensing "a sensor web" or as a single monitoring station.

The main functionality of the device is to monitor, identify, alert and log air quality events that may pose risks to human health and the environment. The device continuously measures levels of air pollutants, and transmits the data over the Internet for cloud-based storage and processing.

The AirBase Sensor Network suite represents a complete low cost solution for remote air quality monitoring. The suite consists of a hardware platform for sensing and data collecting, sending data automatically and periodically over the internet, a software suite for data storage, alerts, signal processing and information generation, and the WEB portal for geo-referenced information, maps, historical retrieval, and report generation. The nodes can be deployed using local Wi-Fi networks, or GSM networks, and need only power supply.

Features:

  • A complete turn-key solution for remote air quality monitoring.
  • Calibration is done remotely through the internet.
  • Control Room Screen.
  • Dashboard with current status with a gauge for each sensor.
  • Graphs for each sensor which displays results averaged every five minutes.
  • Pie charts of the senor history showing distribution of good/moderate/bad conditions.
  • Microsoft Excel file generation based on time range definition and row data/average date every five minutes.

Sensors:

Ozone (O3)

The Ozone sensor is based on a nanotechnology-enhanced, gas-sensitive semiconductor to measure ozone in ambient air. The semiconductor is sensitive to ozone due to surface oxygen vacancies. Therefore, the sensing mechanism is based on decomposing the ozone, and filling of the vacancies, causing a measurable increase in resistance.

Validation tests were exhibiting low drift and tracking similar trends to reference methods with readings almost identical within the specified accuracy level (<± 8 ppb from 0 to 0.1 ppm and <± 10% from 0.1 to 0.5 ppm). Reference instrument: Thermo Electron Model TEI 49C ozone analyzer utilizing UV photometer US EPA Designated Method EQOA-0880-047

PERFORMANCE

  • Calibrated range: 0 – 150 or 0 – 500 [ppb], (fixed after order)
  • Lower detection limit: 1 [ppb]
  • Accuracy of calibration: 6.5 [ppb]
  • Resolution: 1 [ppb]
  • Respond time: 65 [sec]
  • Ambient temperature operating range: -5 to +40 [0c]
  • Relative humidity operating range: 5 to 95 [%]

Nitrogen Oxide (NO2)

NO2 sensors are produced by placing a semiconducting, nano-crystalline metal oxide on a substrate and measuring the conductivity. By adding dopants of noble metals, the sensitivity towards NO2 is influenced and allows a tuning of sensor performance for specific applications.

The sensor uses the following principles: NO2 from ambient air is combusted at the sensor surface, reacting with oxygen atoms/molecules from the crystal lattice. Electrons, which are removed by this chemical reaction, lead to a lower conductivity of the semiconducting material.

Lower detection limit: 10 [ppb]
Resolution: 5 [ppb]
Respond time: 200 [msec]

Relative humidity operating range: 5 to 95 [%]

Volatile Organic Compounds (VOCs)

VOC sensors are produced by placing a semiconducting, nano-crystalline metal oxide on a substrate and measuring the conductivity. By adding dopants of noble metals, the sensitivity towards VOCs is influenced and allows a tuning of sensor performance for specific applications.
The sensor uses the following principles: VOCs from ambient air are combusted at the sensor surface, reacting with oxygen atoms/molecules from the crystal lattice. Electrons, which are released by this chemical reaction, lead to a higher conductivity of the semiconducting material.

Total Suspended Particles (TSP/Dust/Particulate Matter)

The dust sensing principle is an optical sensing system. An infrared emitting diode (IRED) and a phototransistor are diagonally arranged into the device. It detects the reflected light of dust in air. It is especially effective in detecting very fine particles of substances such as cigarette smoke. In addition, it can distinguish smoke from house dust by the pulse pattern of output voltage.

  • Ambient temperature operating range: (-) 10 to (+)65 [0c]

Temperature & Relative Humidity

This dual sensor is implemented in advanced semiconductor technology (CMOS) using specific micro system processing steps to produce the micro sensor structures on specially developed semiconductor parts. The relative humidity sensor element is built out of a capacitor. A polymer absorbs or releases water proportional to the relative environmental humidity, and thus changes the capacitance of the capacitor; this is called the dielectric.

  • Accuracy: ±0.30C / ±2% relative humidity
  • Repeatability: ±0.10C / ±0.1% relative humidity
