[Nhcoll-l] monitoring collections environment

Mon Mar 28 01:31:08 EDT 2022

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.
