How to Improve Air Quality and Efficiency in HVAC with Sensors and Switches (Winners Announced: Win a Honeywell HAQ Air Quality Monitor)!

Hi dougw

I suspect that it can be run from a power supply continuously - looking at the official Honeywell HAQ page at https://sensing.honeywell.com/lp/honeywell-air-quality-monitor , it says the following under the FAQ:

Q: Can I use this in my car?

 

A. Yes! As long as your battery is charged or as long as you have a connection for a USB cable – you can use this device in your car to understand the in-cabin air quality! Do note that for data logging you would need an internet connection so it can upload data to the app, you might use your phone as a hotspot, or the device as a standalone monitor.

It also says the following under specifications and datasheet:

Note: If intended for continuous monitoring, then we recommend having the device connected to a charging port varantly.

I suspect they mean connected to a charging port continuously ... but it seems like everyone's making typos all round.

Thanks Gough Lui ,  that sounds much better.  This will be available On Demand but I will pass these questions onto the presenters as these are all very good questions.

Hi dougw ,

I will be sure to ask next opportunity I get as this was not clear to me either.

An interesting device, but it seems the air quality monitoring is the "new" in-thing to do. Regardless, I think tariq.ahmad, you mean a Honeywell HAQ Air Quality Monitor rather than a Honeywell High Air Quality Monitor ...

I'll see whether I can make it to the webinar, but it's at 4-5am in Sydney, so I have my doubts. Instead, I think I will post my question(s) here in advance in a blockquote:

Air quality monitoring is a hot topic and there are a number of companies using different sensing technologies (including MOX, laser particulate scattering sensors, infrared CO2 detection) and algorithms (some of which are threshold based and others "AI" based) to derive air quality "dashboard" style indications and measurements of different parameters (or their equivalents).

• Could you elaborate on the technologies of the sensors used within the HAQ, the reliability of the readings from these sensors and what studies have been done in order to correlate the IQ% reading with actual cognitive impairment? The datasheet unhelpfully claims that it reports a range of 0-100% with an accuracy of 1%, when I suspect it is a resolution of 1% with an unspecified accuracy. Furthermore, is the CO2 reading based on actual CO2 (i.e. an IR-based sensor) or a CO2-eq measurement (e.g. from a MOX style sensor)?
• What is the sampling rate that the unit achieves for the stated 14-hour normal mode battery life in the datasheet?
• Would it be rigorous enough to say, take this unit and leave it a workplace, take the readings from the device and use it as evidence of an unfit workplace (for example)?
• What sort of Wi-Fi networks does it support? Does it include corporate (e.g. 802.1x EAP authentication) Wi-Fi? Presumably it works with Honeywell Cloud, but does it work (or can it be made to work) without internet connectivity? With internet connectivity, what is the approximate bandwidth consumed by the sensor over the course of a 24-hour period?

Nice capability in this unit.

It might be interesting to have them in our conference rooms.

Can these devices be run continuously from a 5V source?

So we don't need to worry about charging every day.
