How long batteries last in this £10 remote thermometer? |
|
|
Maplins are doing a cheap deal: £10 for a digital thermometer
including a wireless transmitter sensor.
http://www.maplin.co.uk/module.aspx?ModuleNo=34745&doy=6m7
I guess the battery in the transmitting sensor will go before the one
in the receiver.
Does anyone know how long will it be before that happens?

Ten years ago (or more?) I bought a mechanical outdoor thermometer for ?£5
from Woolworth. It is a bimetallic spring coil with a marker over a scale.
As the temperature rises and falls, the coil expands and contracts moving
the marker pointing to numbers on a scale in °C. It is stuck on the outside
of a window glass pane showing readout of outside temperature continuously,
unfailingly. I thoroughly recommend this type of outside thermometer, not
those you need to provide a power source for. Maybe these mechanical ones
are still manufactured somewhere, and you have to search harder on the net.
If you have already bought your battery powered one, then you have no
choice. The specification (in the user's manual) may include an item called
the power consumption or rating of the outdoor module. Comparing this
figure to that of your battery powered wall clock, you can work out very
roughly how long this module will run before the 3 AAA are exhausted,
assuming the module operates continuously as in the clock. The only sure
way, I'm afraid, is to run it!

My cheapo one lasts at least 6 months (not continuous updates - every 30
secs or so) |

Hey, that's the one.....Window Thermometer - 200, 3/4 down the page.
Great find, thanks.

Great. That screwed on thermometer WT4 at the bottom of the page is even
more interesting, and aesthetically, more appealing I think. Because the
sensor is away from the cold glass, it should perform even better than the
coil spring one I have.
But, to be honest, most of these are bought for their decorative value
rather than for their real functional use. Thermometers, barometers, and
wind gauges are in truth, in a modern setting, more as homely furnishings.
They are for display on the mantel piece, as intriguing gadgets for
attention, and not stuck outside the window, out of sight!

The manual claims 12 months for the main unit and 6 months for the
remote sensor. I think I've had mine running longer than this.
Although the remote unit probably has a higher current drain than the
receiver it conserves power by only transmitting brief pulses every 30
seconds or when the temperature changes by more than 0.2C.
Unless they've changed the design, the remote unit uses 2 AAA cells and
not 3 as stated on the web page.

I bought the electronic type, with a wireless sensor, from Lidl about a
month ago, it checks indoor and outdoor temp, has minimum and maximum
readings, and radio controlled time, not bad for £3.99. The wireless sensor
didn't look very waterproof, (described as splashproof), so I put it in the
outdoor electricity meter box, which seems to give accurate readings. Can't
comment on the battery life yet though, it uses the round cell type, but
they are cheap enough now. |

I bought that one as well. My battery in the sensor has been running out
really quicky, given up using it for the moment. Could have a duff one, I
suppose. How long have you had yours?
I put my sensor in a small plastic bag and hung it out of the window!

Yes. I have one of these and they are still available. I bought mine
from a shop for a quid (Poundland?), accuracy is very good and it
withstands all temperatures.
I believe garden centres sell them as well, but obviously more
expensive. They also do max/min versions and probably also humidity
ones as well.

It's probably gasping for breath then. :-)
