Greetings Rowena - At the Georgia O'Keeffe Museum in Santa Fe, NM we FORMERLY used PEM2 loggers and the eClimate Notebook, cloud-based trend graphing and preservation data interpretation for almost 20 years. The units have a real-time LCD readout of temperature and relative humidity and require hand-held downloads using a USB stick and then computer-based uploads to the software. For archiving and non-application analysis, we also kept the data as CSV in microsoft excel. We kept up the calibration and battery replacement schedule, which was minimal and reliable, but the units were sometimes finicky, requiring only certain USB sticks to download the data and rejecting others, while also sometimes refusing to download data altogether. They share the same common resistance sensors as Hobo Units.
We are now a year into replacing all of our PEM2 units at our two historic homes, 10 exhibition galleries and four collection storage areas and library / archives with Conserv data collection units and cloud based software - https://conserv.io/ . The units report in real time to a very UX friendly cloud-based software using LoRaWAN (a long-range radio rework technology), not Bluetooth or WiFi. The user interface is far more intuitive than EClimate Notebook in my opinion and, I think more importantly, Conserv has built an amazing community of users who actively interact and discuss issues related to climate, integrated pest management, light exposure and a growing number of physical preservation parameters. We are increasingly happy with this option. The data is open and non-proprietary, so you are not locking your data up in a code-vault that only Conserv can help you open up. It's CSV data, you can archive it and chart it in Excel anytime you want. Have a look.

We want to start taking humidity readings in our historic house museum. Does anyone have a view on better options? In this day and age, is it possible to get something that tracks humidity levels into an app or website, or do they still all require active monitoring?
Thanks so much,
Rowena
