Installing a wireless outdoor thermometer is an excellent way of keeping track of the
weather from the comfort of your own home. Sensors can be placed around the garden in addition to the home. The readings are then sent wirelessly to a receiver in the house which displays the data from all of the sensors.
A wireless outdoor thermometer can be an extension of any computerised automated home control system. Sensors located in garden glasshouses can be configured to trigger heaters when the ambient temperature drops close to freezing point. Internally, air conditioning can be set to come on when the home gets to hot.
Depending on the budget available, additional sensors can be purchased to detect the relative humidity, and pressure sensors to give atmospheric pressure. When selecting the make and model, check the full list of functions. A more complete weather station will give you a broader picture of the current weather conditions, and the moisture levels in your home. Generally the units have a transmitting range of up to 100 ft, which is sufficient for everything other than a stately home.
Whether you are ready to include a wide array of sensors or not, it is prudent to select a model which has the capacity to allow additional environmental sensors to be purchased at a later date. You never know if you will want to expand your gadgets, and it is better to have the functionality, than to have to sell your unit and buy again from scratch.
Consider how you will be powering the unit and the sensors. The base unit, or handset, will require batteries although some can be operated on mains electricity. The sensors will require power too, so check the battery requirements for these. Some sensors are solar powered and will increase the lifespan of the batteries. Most units come with easy to install instructions, so read these carefully before setting up the equipment.
First of all you will need to insert the batteries into the base unit and the sensors. There is often some degree of calibration required and internal clocks will need to be set. The base unit will also need to be synchronized with the sensors. It is far easier to do this in the home, rather than finding out they do not work correctly when you have put the sensors in place.
When all of the sensors are working, choose suitable spots around the home and garden. The units should not be located in direct sunlight as this will give erroneous readings, and remember that you will have to change the batteries from time to time. Placing them in easy to reach spots is a good idea. You will then be able to sit back and monitor the environment from the comfort of your own home.
