[Nhcoll-l] monitoring collections environment

Mon Mar 28 10:28:49 EDT 2022

Thank you! I definitely go with HOBO in our old buildings.

As we are planning brand new building I am also seeking for a central real-time monitoring system. Any suggestions?

Head!

Once again concurring with Andy:

Yes, with the Bluetooth units it's just a matter of a minute or so to stand near the unit (30 m or less), download the data, and relaunch the logger. As Andy says, the batteries they use are cheap and last 6–12 months (the unit will give you plenty of warning that the battery is getting weaker).

That works well for situations where you do not require real-time monitoring. There are units that can be plugged into Ethernet, or that can link to a WiFi wireless network, but they are indeed significantly more expensive. Obviously, they also require a nearby Ethernet tap or active wireless (which is often a problem in collections spaces).

If you don't need real-time, the completely stand-alone nature of the HOBO loggers (for example, the MX1101 [costs US$145]) makes it really easy to put sensors where you want them, not forced where you have wire or WiFi connections. It is possible to augment them with an "MX Gateway" (costs US$375), which can connect between Ethernet or WiFi and one or more Bluetooth loggers that are within Bluetooth range. That provides the possibility of starting with standalone monitors that you download by walking past, then adding the MX Gateway later if budget permits and near-real-time is needed.

Not sure what you mean by a central montoring system but essentially with these bluethooth units all you need to do is get close to them and you can download to a smartphone, tablet or computer.  There are central monitoring systems available but they are much more expensive and require costly installation as far as I am aware.  The nice thing about these is that they are self-contained and cheap.

  *   battery powering means that there is need to change batteries regulary – would it be better if the loggers are connected to main current?

We only have to change the batteries in our loggers every 5-6 months if that and it is a very easy process.  They all take the CR 2032 watch batteries.  Again, I think there are units that can be connected to main current but will require costly installation.  These units can be placed anywhere and moved at any time.

Thank you.
So the HOBO seems to be a good choice, but I still have few questions.

  *   the bluetooth does not seem to give a opportunity for a central monitoring system
  *   battery powering means that there is need to change batteries regulary – would it be better if the loggers are connected to main current?

Best!

I concur with Andy's recommendation of Onset HOBO data loggers.

We've used a number of them for quite a few years. They have been remarkably stable and dependable. All the units we deployed in 2014 are still functioning just fine (along with newer ones we've purchased since then).

Here in Southern California, we can even get away with using an "indoor" sensor outdoors in an appropriate outdoor temperature instrument screened housing. But I don't recommend that for locations with actual weather.

I would suggest HOBO recorders from Onset.  There are various different models that are battery operated and can be downloaded through Bluetooth connection to your smartphone for transfer to your computer.  They also have an LCD display for real time monitoring.

The ones that we use for monitoring our collection spaces are these:  https://www.onsetcomp.com/products/data-loggers/mx1101<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.onsetcomp.com%2Fproducts%2Fdata-loggers%2Fmx1101&data=04%7C01%7Cabentley%40ku.edu%7C309067edd65f448915c808da0e366a12%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637837924273497772%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=gT5x2WB55Qw5LK0z9b8IZGqVhLSCbLA3D8G7uOn9SPQ%3D&reserved=0>

We have been using them for a long time and they are great.  Small enough to monitor microclimates within cases as well as entire rooms.

Hi!

Can you please suggest good monitoring systems for collections in Europe.
What do I need (internet cable, wifi, electricity) to install the loggers into collections?

Best regards!
