<div dir="ltr"><div dir="ltr"><div>Once again concurring with Andy:</div><div><br></div><div>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). <br></div><div><br></div><div>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). <br></div><div><br></div><div>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. <br></div><div><br></div><div><div><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div><div dir="ltr">-Dean<br>-- <br>Dean Pentcheff<br><a href="mailto:pentcheff@gmail.com" target="_blank">pentcheff@gmail.com</a></div><div dir="ltr"><a href="mailto:dpentche@nhm.org" target="_blank">pentcheff@nhm.org</a><br><a href="https://research.nhm.org/disco" target="_blank">https://research.nhm.org/disco</a></div><div dir="ltr"><img><br></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Mar 25, 2022 at 6:34 AM Bentley, Andrew Charles <<a href="mailto:abentley@ku.edu" target="_blank">abentley@ku.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

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.<u></u><u></u></span></p>
