CONTINUOUS AIR QUALITY MONITORING

MONITOR AIR QUALITY WITH EASE

What it does ? And why?

What it does ? And why?

  • The box can take gas sensors output 4x(4-20mA) +5 (0-5V) differential input and send to Azure Cloud Platform.

  • To configure the sensor data and calibration-custom middleware app is available. No need to do any Firmware coding. Just configure units and calibration via Mobile app.

  • It has integrated GPS/GSM module for tracking and web connectivity through SIM

  • AQI computation at Azure server end and display through graphs.
  • CAAQMS application
    features

  • Add device under a asset

  • Remote Sensor configuration from anywhere.

  • Device connectivity.

  • Sensor calibration.

  • Temperature/Humidity correction is supported.

  • Sensor real-time data monitoring.

  • Sensor trend data view.
  • Device Connectivity Configuration

  • Once the on-boarding process is completed wi-fi list will appear.

  • Tap on a item from available network list.

  • Enter the password for that network.

  • Tap login and wait for the process to complete.
  • Real Time Monitoring

  • Click on Drive from side menu.

  • Then select an asset to monitor.

  • Monitoring page shows—

  • 1. Current sensor status (online/offline).

    2. Last data report time and last reported value.

    Sensor Trend
    Data

    Sensor data can provides following:

  • Trend data:

    Last one hour data.

    Last six hours data.

    Last seven days data

    Last twenty eight days data.
  • Sensor Calibration

    Sensor Calibration

    IOT middleware device performs internal logical calculations to get sensor values.

    It takes Factory offset and Zero offset also into consideration.

    At time of sensor configuration both Factory offset and Zero offset values are set.

    To calculate factory offset—

  • Tap on factory offset in sensor parameter configuration.

  • Enter the expected value and currently value of the sensor output.

  • Hit on save and this will calculate the Factory offset.
  • By default, sensors provide raw data in form of current and voltage from gas sensors. But our device can convert the raw data into calibrated data based on two offsets—

  • Zero Offset.

  • Factory Offset.

  • Sensor reading also varies based on the temperature and humidity, that’s why our device provides correction based the following compensation data—

  • Pressure compensation

  • Temperature Compensation.

  • Humidity Compensation.

  • And while providing the factory offset you don’t need to provide or calculate the factor. All you need to do is provide the raw reading from the sensor and expected reading and the factor will auto-calculated.

    All the background data with time stamp will be stored and can be downloaded.

    Device Maintenance

    Device Maintenance

  • So, you don’t need to worry about doing on-premises maintenance, as long as the device is connected over network we can regularly push updates to keep your device updated with latest features and secure from software threats.
  • And in case anything goes wrong, we can remote debug the device to find and patching the issue without physically connecting the device.
  • Trend data:
  • OTA. Remote Debugging.

    The Optical Particle Monitor unit is used for particulate matter monitoring 2.5/10 PPM. It can also provide PPM 1.0. The sensor module used in this CAAQMS design measures particles from 0.38 micron to 17 micron diameter accurately, repeatedly, and with minimal maintenance using the patented ‘pump-less’ design. It will still have a small inbuilt fan. It can be noted that unlike other OPC, it does not use a Pump along with a filter that gets very dirty in a typical high pollution environment. It uses a different approach. The patented OPC-N2 uses an elliptical mirror and dual-element photo-detector to create a ‘virtual sensing zone’ in free space at the centre of an open scattering chamber. The OPC-N2 classifies each particle size, at rates up to ~10,000 particle per second, recording the particle size to one of 16 “bins” covering the size range from 0.38 to 17 μm. The resulting particle size histograms can be evaluated over user-defined sampling times from 1 to 10 second duration. This histogram data and air temperature are transmitted via an SPI interface to a host computer.
