Summer months are fast approaching, and if you are in the states (or cities) in the United States that experience a lot of sunny and warm days, having access to a pool in your home is bound to bring you a lot of comfort and relief.
However, beyond focusing on pool safety, you also need to ensure that the pool’s temperature is optimal so you're comfortable while taking laps from one end to the other. But, the question is, “How do you measure the pool temperature without taking a dip in the water yourself?”
This is where wireless pool thermometers come into play, perfect for remotely monitoring pool temperature. So, if you're curious about how to monitor pool temperature remotely, this in-depth guide will explore it all.
Why Do You Need a Wireless Pool Thermometer?

Jumping and splashing in the pool during the hot summer months is only comfortable when the water temperature is. Can you imagine stepping out to the pool and unknowingly taking a dunk, only to realize that the water is likely boiling hot?
Nobody wants to experience that (and you don’t have to). Here’s how a wireless pool thermometer comes in clutch:
1. It Makes Things Convenient
Let’s say that the weather is perfect for a pool party. Sure, you can step out of your home around the patio to head to the pool to check the water temperature, but the heat from the sun is bound to make you second-guess things. This is where a wireless pool thermometer comes in handy. It eliminates the manual and physical aspects of checking the temperature.
2. It Provides Accurate Readings
Investing in a reliable and good-quality wireless pool thermometer means that you won’t have to worry about the accuracy of the data. These devices take into account factors like air temperature and humidity, ensuring you get accurate readings on the app.
3. It Allows Trend Analysis
If you want to make enjoying a swim in the pool a regular thing during the peak summer months, a pool thermometer is a great way to keep track of the data in one place. For example, it allows you to track back to how the temperature was a week ago, without you needing to keep track of it manually. Also, if there are sudden or drastic changes in the temperature without any triggers, it could be a sign of faulty sensors, allowing you to analyze the issues ahead of time.
4. It Ensures Timely Maintenance
Lastly, having a pool thermometer allows you to maintain the pool temperature within the desired range. So, if you don’t want to indulge in expensive and untimely maintenance of the pool, keeping track of these readings should make your life a lot easier.

To ensure you get the most out of your spending, choosing the right wireless pool thermometer is key. The following are a few factors to watch out for:
1. Transmission Range
This is without a doubt the most essential feature to look out for. If you have a large house where the distance between the pool and the rooms is considerable, you want to invest in a pool thermometer with a longer transmission range. Also, the connectivity technology, such as Bluetooth, Wi-Fi, or IR, needs to be taken into consideration for accurate readings.
2. Temperature Range
What temperature range will the sensor record? This is another factor worth looking into. Different sensors have different temperature range coverage. For example, a hot tub might require a thermometer that can record over 100 degrees Fahrenheit, while a standard pool can do with a lower temperature reading. So, explore the range before making a final purchase.
3. Accuracy of the Reading
When buying a wireless pool thermometer, you want to ensure that the readings are accurate and without discrepancies. Ensuring the accuracy of the reading is another factor you can’t miss when making a purchase. Usually, a well-calibrated and accurate measurement with a tolerance of +/- 2 degrees is considered ideal.
From checking HVAC systems to cooking and medical applications, our guide on infrared thermometer uses covers the most practical ways to get the most out of these versatile tools.
Final Words
Monitoring your pool temperature remotely is no rocket science, provided that you have access to the right tools and devices. Investing in a good-quality wireless pool thermometer can be a game-changer for you, enabling you to keep track of the temperature and humidity around the pool before you go down and enjoy the experience yourself.
