In ye olde days, there was one surefire way in which one could discern the temperature of an upstairs bedroom. Namely, go along the hall, up the stairs and along the top hall to said bedroom, open the door and insert one's head.

Now there is no need to indulge in such energy-wasting, health-inducing activity. The alternative is, quite simply, to invest in the climate control equivalent of the bridge of the Starship Enterprise.

Permit us to explain. The majestic Clima Control device, from those masters of climatic technologies at Oregon Scientific, is a four-room sensing system that enables one to keep tabs on the climatic conditions of up to four different rooms all at once. Marvellous.

The basic unit comes with two sensors - one internal and one external - with complete expandability up to four internal sensors. When fully connected, each rooms' conditions - temperature and humidity - are highlighted in bold easy-to-read numerals on the large flat-panel LCD display of the base unit. Meaning you can keep an eye on the toastiness of the kids' bedrooms without so much as moving a muscle from your prime slot in front of Holby City.

If that wasn't enough, the Clima Control device is also dedicated to looking after the very fabric of one's building, with the help of an advanced built-in Mould Detection function. Meaning that this wondrous unit has the innate intelligence to spot when damp conditions are prevailing.

In short, Clima Control gives one almost omnipresent abilities, only just short of controlling the weather itself. Sort of.
