This article lists some popular FAQ’s concerning the Airthings for Business wireless Air Quality monitoring solutions that can be found here:
Q: How many Airthings Sensors such as the View Co2, View Plus, Wave Plus and Wave Mini may be connected to a business hub at the same time?
A: This depends on the type of sensors. We find 30 Wave Plus or Wave Mini’s are absolutely fine, with the View Plus/View Co2, as they take more bandwidth, we recommend no more than 15-20.
Q: What connectivity options does the Business Hub provide in order to get data off site?
A: The Airthings for Business Hub comes with built in cellular connectivity as part of the subscription however it also features an RJ45 ethernet port for connection to a LAN with internet access.
Q: What is the ideal mounting/placement location for Airthings sensors?
A: Typically, to get an accurate indication of the air quality in any given space the sensors should be mounted on a wall between 1.2 and 1.8m (around average head height). Sensors should NOT be placed near windows, in the airflow of any ventillation systems or in direct sunlight.
Q: How many Airthings for Business Hubs will I need to provide coverage for my building?
A: This is a good question and not one that can be answered with 100% certainty without prior knowledge of the environment they are going into… However given a typical multi-storey building of concrete construction with medium-open plan layout you should plan for at least 1 hub per 2 floors or around 40 meters range taking into account walls/floors according to the following excerpt from Airthing’s own KB:
In general, we state that Smartlink (= the communication protocol the Hub uses) can easily penetrate 3 thick concrete walls/floors or 10 drywalls or 1-2 floors up/down in an office building.
In terms of distance, we recommend placing a Hub within 40m of a sensor. But this again depends on the number of walls, the layout of the room,… The more walls between the Hub and a sensor, the closer you will need to place a Hub.
Q: How do I integrate Airthings for Business into my BMS or Tridium Niagara 4 environment?
A: Airthings sensors report their data into the Airthings cloud, there is no direct local interfacing, however their cloud sports a well documented API and any system that can function as a HTTP/REST API client may integrate sensor data this way.
This is made easy for users of Niagara 4 with the One Sightsolutions module ossEasyAPI. It includes semi-automatic components which take your Airthings authentication details, connects to the API and brings in all your sensors with just a few button clicks. All sensor data can then be accesses via the usual slots/points in the Niagara framework.
Q: Is Airthings for business a subscription-only service?
A: Yes, After the initial hardware cost, this ongoing subscription is required to maintain access to the Airthings cloud including the dashboard and API.
