Difficulty: Moderately Easy
Things You’ll Need:
- A wireless outdoor thermometer (Shop around. There are a lot of good, inexpensive ones out there with a variety of features).
Choosing the right unit
Step1
Decide on a price range, and the features you want. Don't pay extra for features you don't really want. Major discount stores are good places to start.
Step2
Choose a unit that is expandable. Some units have the option of installing more than one sensor. Even if you don't need it now, this could be very handy later.
Step3
Compare what kind of batteries the different units use. Try to pick one that uses a battery type that you already commonly use. This way you can buy batteries in bulk.
Installation and synchronization
Step1
Remove the base and remote units from their packaging, and make sure they are in good condition. Read the instructions.
Step2
Install the batteries in both units.
Step3
Synchronize the two units by following the manufacturer's instructions. Most such units must first be synchronized, in order to be able to properly communicate with each other. Additionally, some units also use a radio clock which also must be synchronized and set to the local time zone.
Step4
Decide where you will use the base unit before installing the remote. The base and remote need to be relatively close together.
Step5
Locate a good spot to mount the outdoor remote. There is typically a sticky pad on the back for attaching the unit. The base unit should be located within 50 feet of the base unit in order to work properly. Choose a place that will not receive a lot of direct sunlight, as this will give you false readings. Also choose a place that is easily accesible. You do not want to climb a ladder every time you need to change the battery. Finally the area should be sheltered. A few stray drops of rain won't hurt it, but it should be shielded from heavy downpours. Outside a window is good, as long as a screen does not block access to it.
