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

[Simon Moore]

I also used Tinytags and they are very useful and versatile, especially if you have to monitor buildings that are well beyond the range of a telemetric system.

I set them to read every hour, resulting in easy-to-interpret readings and was enough to time give an alert when a museum’s roof might have started leaking due to storm damage.

With all good wishes, Simon.

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.

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.
