[Nhcoll-l] temperature and rel. humidity datalogging system

[Christian Baars]

Thomas,

We use a Meaco telemetric system https://urldefense.proofpoint.com/v2/url?u=http-3A__www.meaco.co.uk_radio.htm&d=AwIFAw&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=6Fv1lfV5fhmH3zN792ESnn74KUEgWt1K-ufR41RywZs&s=SpKFYIfRT8D0MHNej7kWsBaA_Zthq7Yhe2XizE3NHkM&e= . The system comprises battery-operated HTX transmitters (to measure T, RH, and, in a few galleries, lux and UV), a centrally located receiver (which currently transfers data onto a networked PC, soon to be replaced with a server which will make data storage easier and safer) and, as this is a large historic building with thick concrete walls, a number of repeaters dotted around the building to boost the signals from transmitters to ensure they reach the receiver. While it does not come entirely without flaws it is easy to use and reliable - certainly, as experience has shown, more reliable than the monitors used by our Buildings & Estates Department as part of their building management system.

In addition, we also employ a number of self-contained Tinytag Ultra 2 data loggers https://urldefense.proofpoint.com/v2/url?u=http-3A__www.geminidataloggers.com_data-2Dloggers_tinytag-2Dultra-2D2&d=AwIFAw&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=6Fv1lfV5fhmH3zN792ESnn74KUEgWt1K-ufR41RywZs&s=40kpbz6UzhvIuePkBs98l9imQ2BFFD_JX3wBTLcqWGA&e=  for monitoring T and RH in awkward spaces. These are very easy to use and extremely versatile but have the disadvantage of having to be removed once their internal memory is full (how quickly this happens depends on the monitoring interval, e.g. if you monitor once every hour the memory will last longer than monitoring once every 15 minutes) to connect to a PC and download the data.

Kind regards
Christian

Hello everyone,

I want to establish a data logging system for temperature and relative humidity in the vertebrate paleontological collections at the Museum für Naturkunde Berlin, so I was wondering with which companies you had good experience. I am looking for a wireless system with a base station so it can start small but is expandable in the future.

Thanks and all the best

Thomas
