Wireless Temperature Sensor
When You Want to Know the Temperature Somewhere Else

A wireless temperature sensor is great if you want to record the temperature of something that’s moving, too hot or too cold for comfort. Or if you can’t or just don’t want to be there, wireless temperature sensing makes it possible.

Why not bring the temperature back to where you are, when you want it, without having to be there... or putting up with the inconvenience of wires.

Remote temperature sensing can alert you if there’s an unwanted temperature change and can be as simple as a single self contained wireless temperature sensor and electronic display, or you can scale it up to a network of wireless temperature sensors.

Or it can be as complex as an infrared scanner measuring sea surface temperature from a satellite. Whatever the size of your application, you’ll want to know the temperature accurately, reliably and at reasonable cost.

There’s a trend for electronic devices to have as many functions as possible, because they often already have the necessary electronic hardware on board to carry these out. So for little or no extra cost, developers can add extra functions to a product that may give the manufacturer a market edge over the competition. Here’s an example.

There are some home weather stations available that allow you to wirelessly connect remote temperature sensors to them. So you not only get weather information, but you can also add on wireless temperature sensors that let you remotely monitor the temperature in your spa, swimming pool or fishpond… or anything else. The temperature is just displayed alongside the weather information. Here are some bottom line benefits of using wireless technology for temperature measurement.

Benefits of using a wireless temperature sensor

Here are some of the benefits you can gain by using wireless sensors...

Reduce Costs

You benefit in two ways...

Because you don’t have to run wires between these sensors and a display or recording device, they are far easier to install than their wired equivalents, so ‘day one’ installation costs are less.

Your ongoing costs may be significantly less too, depending on the application. The temperature information comes to you… you don’t have to go and get it. This saves time.

Get temperature readings as soon as they happen

If you’re a long way from the thing you want to measure, it can be reassuring to know that the measurement system is actually working OK. You can see the temperature in real time, as it happens, anytime.

Wireless can make an impossible task possible

A wireless system can let you get temperature information from places, or under conditions, where it just wouldn’t be easy or possible to do it any other way.

Want to know the temperature of something that’s moving? You usually can’t use wire, but you can use wireless.

Provided the temperature transmitter and the receiver stay within radio range of each other (at least some of the time) then wireless can be very reliable and practical. Can’t, or don’t want to be there? You don’t need to put up with the discomfort of having to access difficult-to-get-at, cramped, sealed, dirty or hazardous locations to get temperature readings.

Using wireless temperature sensing around your home

There are lots of ways you can use a wireless temperature sensor around home to make your life better. Here are some ideas...

Indoor/outdoor temperature sensing

The air temperature affects us all, and can be useful information… Is it getting hotter or cooler? Should I take a jacket when I go out?

To get representative temperature readings, take care where you install your sensor. If you want to measure air temperature, make sure that air can flow around the sensor and make sure you put it in the shade. Direct radiation from the sun would make the temperature appear higher than it really is. And don’t mount a sensor on a large structure that can store heat, such as a concrete wall. These could keep the sensor warm long after the air temperature has fallen. A small wooden structure is better.

Wireless thermometer for spas, pools and fish ponds

Want to know when the pool is warm enough for a swim?

Get a wireless temperature sensor that floats on the surface of your pool and transmits the temperature information to a display or base station in your house.

Look for one with a large display that you can read easily (without glasses) and an alarm you can set to let you know when the water goes into or outside of your comfort range. Knowing when to change the batteries is also useful, so look for a unit that displays battery health. It’s also useful if the base station displays air temperature.

Check that any unit you’re considering has a radio range greater than the distance between your pool and the display. Many wireless thermometers are good for around 100m / 300 feet. And look for a unit that displays the temperature in the units you want ie. Fahrenheit or Centigrade/Celsius, or better still, a unit that does both, so you can choose. That way you could send one as a gift to someone in a different country.

Freeze alarm

When water freezes, ice can lead to problems. If you know that freezing is imminent, or has already happened, it can help you manage and avert a potential disaster. If ice forms in pipes it can burst them.

Ice forming on walkways can lead to a hazardous situation that could result in broken bones. You certainly don’t want you sprinkler system starting up under conditions that are likely to cause ice build up. There are ways to disable sprinklers under freezing (or rain) conditions.

Barbeque or smoker temperature sensor

If you don’t want to be distracted by constantly having to measure the temperature of the meat on your BBQ rotisserie, you can get a wireless temperature sensor to do it for you.

Monitor smoking chamber and internal meat temperatures. Some units have timers that count up or down and have alert thresholds.

Baby room temperature

Some baby monitors also monitor room temperature and alert you if this moves outside a programmed comfort range of perhaps 60-70F or 15-20C.

Using a wireless temperature sensor beyond the home

Beyond the home, there are many commercial, health-related and scientific applications for the wireless temperature sensor.

Wireless temperature sensors are great for tracking the ‘temperature history’ of perishable goods, such as food products, during transport and storage. They can improve the safety and comfort of hospital patients or continuously monitor the temperature of the environment.
