AQMesh operation

Installation

AQMesh is very simple to install: one of our users installed 20 pods in London in a morning. There are some simple steps and the video shows how easy it is to get up and running:

  1. Unpack, screw on antenna and remove pod from mounting (single security screw)
  2. Select location and secure mounting
  3. Connect battery and start initialisation sequence (10 minutes)
  4. Mount pod in position (single security screw)
  5. Log onto the AQMesh server to enter location coordinates and check data is transmitting
  6. Wait for data to stabilise (automatic flag)

Watch the 1 minute video:

There is also a short video showing installation using steel banding instead of post clips, and a full length installation video with narration to guide you through each step of the way.


Standard operating procedure

Please view the standard operating procedure which provides users with all the necessary information to get the best results with AQMesh.


Pod settings

Readings can be from as short an interval as 1 minute. The default setting is hourly readings, as this maximises the battery life and is suitable for most applications.

Transmission intervals can also be set by the user – the default is hourly.

Changing pod settings

User access is by secure login. Permission levels can be set by user to allow access to be restricted if required.

Online access allows the following to be viewed or changed:

  • GPRS connectivity and data transmission frequency
  • Reading frequency
  • Sensor serial number (this must be changed if a sensor is replaced in order to pick up individual sensor characteristics)
  • Time zone
  • ppb to µg/m3
  • View graphs and compare pods
  • Download data

User modes

Online user access to the pod is available on two levels:

1) Default settings

As simple as possible for any user

2) Advanced settings are accessible by all users

  • Allows improvement in accuracy through scaling
  • When co-location with a reference station is possible
  • Scaling using regression analysis

More advice on how to use scaling on AQMesh in Advanced mode is in Online support and user FAQs


Power options

AQMesh pods can be powered in various ways. This allows flexibility of location, dependent on application or project type. The table gives an indication of how long a pod will remain powered using the different power options available.
