When you want to know how hot or cold it’s been getting lately, there are a few ways to get this information direct from your smartphone. The humidity level is also useful to get an idea of as it affects how overheated your body becomes even if the temperature isn’t excessive.

Now, let’s explore some of the ways to get the temperature or humidity level direct from your phone.

Getting the Rough Local Temperature

Pulling up information about the recent temperature in the local area or what the highest and lowest temperatures have been recently is accessible through a web browser. There are plenty of websites that will pull up information for a city and state. This gives you a sense of what it was like in the rough area, but not directly at your property. It’s strictly the outdoor temperature from whatever weather station was nearest to the location, but no better than that.

How relevant that kind of temperature reading is depends on what you need it for. If you’re more interested in the indoor temperature within certain rooms in your house or outdoors on your patio under the shade, then it won’t do you much good at all!

How to Get Indoor and Outdoor Temperatures Away from Home

When you want to get the temperature in your toddler’s room or to check on the office where your computer server is located, then a rough outdoor temperature from a commercial weather station isn’t going to cut it.

You need a remote temperature monitor that comes with a thermometer and a hygrometer to get a proper sense of both the temperature and humidity levels. These devices have sensor packs that can read and collect temperature and humidity information regularly and transmit it wirelessly using Wi-Fi or Bluetooth.

Mobile Apps to View the Data

The better wireless temperature monitors provide their own mobile apps. Often there’s one for iOS and another for Android. People interested in getting one of these monitors can choose the best product that offers a mobile app for their platform of choice.

The information collected from the monitors is collated and then provided to the mobile app. The app is then able to provide information to the homeowner about the temperature in the rooms where there is a monitor placed or outdoors if they’re using an outdoor-compatible version there too.

Some monitoring systems have the potential to add more than one device in different rooms to get multiple readings whereas others are intended to be a single monitor solution.

What’s the Level of Precision for Monitors?

If you’re worried about the accuracy for temperature and humidity monitoring, you needn’t be. While each brand and model differ in their specifications, the range of temperatures picked up by sensors is usually around -35°F up to 120°F. The accuracy is a good indicator with the readings only varying by up to 0.5°C for many products making the temperature information reliable indeed.

The humidity readings for monitors that also provide this feature often fall in the wide range of 0 to 100% level with an accuracy variance of 3-5%. That’s certainly specific enough to be valuable as differences in humidity levels only tend to matter when they start jumping by 5-10 degrees in a short space of time.

How Are Temperature Monitors Powered?

The individual monitors are almost always powered by batteries. This allows them to be placed exactly where you wish them to go without having to worry about a power outlet being nearby. Most run on a couple of AA batteries whereas some use accessible coin cell batteries instead. Each monitor has a low power usage, so a set of batteries typically lasts 6-12 months depending on the power usage.

When you need to get a reliable idea of the temperature indoors or just outside your home and view it on your mobile device from anywhere, a wireless temperature monitor is an ideal solution. They’re reliable enough with their sensors to provide precisely the information necessary and can run continuously as an ‘always on’ solution.
