Used during an
investigation, can be a useful tool. As the recording can be over the
entire length of the investigation, so logs any temperature change and
the time, it therefore makes it easy to tell if there were any strange
sudden rises or drops in temperature. Also good to compare with any
video footage, if a séance is held, and people report feeling warm or
cold, as long as the time on the video camera is checked to be
accurate before recording begins, it can then be checked against the
log to see if any reported change was picked up.
That doesn’t mean to say if the log didn’t see a change there wasn’t
one, it could have be a localised cold/hot spot. Placement of the
loggers is very important, it may sound obvious, but placing on a
window ledge is not the best location! It maybe a handy place, but
once the night sets in, the outside temperature will drop affecting
the logger, doors that are open frequently also create drafts etc, so
careful thought as to location should be given before placement. On
the plus side, they can be set up in advance of the investigation
beginning and then not touched again until the end when they can be
collected up and the data analysed.

The type as pictured are
sometimes referred to as ‘break-beam’ style. Basically does what it
sounds like it should, the alarm sounds when the ‘invisible’ beam
between the transmitter and receiver is broken.
For use during paranormal
investigations, great for setting up around trigger objects (objects,
which are placed in the hope that the spirit will take an interest in
them and move them, e.g. old coins, children’s toys etc). But should
be used in conjunction with ‘locked-off’ camera (a camcorder or camera
set up to record an area of interest or trigger object). After all its
nice to know something has moved a trigger object, but even nicer to
try and rule out natural causes for the movement! |
