Most indoor and outdoor thermometers function similarly when measuring indoor and outdoor temperature. The most significant difference between the two is the ability to endure weather conditions. Indoor thermometers are not designed to withstand rain, snow, and UV rays, whereas an outdoor thermometer has waterproof and ruggedly constructed housing to endure the elements. Q. Are digital indoor thermometers accurate? We considered several criteria when selecting the best indoor thermometers for our hands-on tests. Our list included indoor thermometers that sync with a smartphone for remote monitoring, making them ideal for greenhouses, wine cellars, humidors, and animal enclosures. We also tested simple units that weren’t wireless but allowed us to see the temperature and humidity at a glance.
The ThermoPro can also take readings within a tenth of a degree, and it refreshes every 10 seconds. The TP49 uses one AAA battery (included). All in all, we found this to be an accurate and unobtrusive indoor thermometer at an attractive price. Many indoor thermometers also function as hygrometers that can measure the percentage of moisture in the air between humidity ranges of 0 percent and 99 percent, within a margin of error of +/- 2 percentage points. Unlike the other indoor thermometers we tested, the LaCrosse Technology Thermometer can be plugged into an electrical outlet as well as run on battery power. This is a great option for folks (like us!) who always seem to be scrambling to find fresh batteries. We rated the LaCrosse as relatively accurate, but when we made the side-by-side temperature comparisons, it was fully 1 degree below the majority of the other thermometers, and its outdoor module registered 0.5 degrees above the temperature detected by our weather station. It’s still plenty accurate for those who want to know the general temperature indoors and out. We found that the outdoor module must be within 50 feet of the base unit to register the temperature, but it will read through walls. Wireless Indoor Outdoor Thermometer: The easy-to-read LCD display, acting like an outdoor thermostat, provides current indoor and outdoor temperature with precision and accuracyThe only improvement I can think of for this would be to have the "High/Low" record be so it can be for the last 24 hours (as they have it now), or have a toggle switch where it would display for the actual date (display the high and low from midnight to midnight).
Ahead, learn what to look for when shopping for the best indoor thermometer for a home, and find out how the following products earned a spot on our lineup. Accuracy is crucial when it comes to an indoor thermometer, but other features are also important, including size and connectivity. Here’s what matters in an indoor thermometer. Temperature Range and Accuracy At first, it was hard to believe that the SensorPush is a thermometer hygrometer—the mini module looks more like a keychain fob, which can be hung from a chain or cord if desired. The SensorPush has no visual display, but it transmitted ample in-depth data to our smartphones via Bluetooth.First, we installed the Govee Home app, which walked us through the rest of the setup (a Wi-Fi network is required). The app allowed us to see temperature changes over hours, days, and months so we could analyze the temperature and humidity cycles and tendencies. The thermometer/hygrometer comes pre-calibrated, so it worked right out of the box. We put it alongside the other modules we tested, and it was within 0.1 degrees of the most consistent temperature and humidity levels. We rated it as highly accurate.
Precision is critical when it comes to an indoor thermometer, and AcuRite’s manufacturer claims this thermometer has a narrow 0.5-degree range of error, with data updated every 10 seconds. This model requires calibration, which involves pushing a series of buttons, but this only took us a few seconds and then the thermometer was good to go for testing. We could see the indoor temperature and humidity data on our smart devices. The SensorPush recorded temperatures and humidity levels that were consistent with the other indoor thermometers we tested simultaneously, so we judged it to be accurate. One of the nicest things was the ability to look at the temperature and humidity records in a chart format. That allowed us to see how the levels changed over hours and days. Those wanting to monitor temperature and humidity levels in more than one area of the home need look no further than Govee’s mini thermometers. Govee’s mini-modules do that job efficiently, and they’re small enough to be placed virtually anywhere without being obtrusive. Each of the three sensors comes with its own lanyard for hanging on a nail, screw, or hook. Most indoor thermometers can read a broad temperature range, making them suitable for monitoring such extreme indoor environments as a refrigerator or freezer. Some indoor thermometers are capable of reading temperatures as low as -50 degrees Fahrenheit and as high as 145 degrees Fahrenheit. These thermometers are also able to take accurate readings. Although most thermometers have a margin of error of a degree or two, the most accurate models are to within half a degree. The only downside was that we couldn’t monitor the data remotely; since these Govee modules are only Bluetooth capable. They were accurate when located within about 75 feet of our smartphones. This is par for the course for Bluetooth devices, but be aware that you won’t be able to read them when you’re away from home, as you could with WiFi-capable devices. Still, we felt they were among the most accurate, and the ability to monitor several rooms was a winner in our book.
Feedback
Some indoor thermometers are capable of connecting to a smartphone via Bluetooth, allowing the user to monitor environmental conditions remotely. Quality indoor thermometers can also store months and even years’ worth of data via a cloud storage service, which is useful for those who need to monitor the environmental conditions in a greenhouse, wine cellar, or humidor. The use of Bluetooth gives these thermometers a range of a few hundred feet. Some can even be paired with a compatible smart-home hub, allowing them to send alerts and data to a smart device in virtually any location. Additional Features
Basic and straightforward, the Taylor Indoor Thermometer isn’t wireless; it simply offers indoor temperature and humidity levels. But the design of its colorful comfort display is a great feature: The top half of the screen displays a digital dial with an indicator that ranges from Dry to Comfort to Wet to show how comfortable the combination of temperature and humidity feels in the home. The Govee wireless thermometer hygrometer alerts you to the climate conditions your fur baby is experiencing in real time and by collecting indoor temperature and humidity data for monitoring fluctuations. Strong Remote Thermometer: The wireless outdoors thermometer sends outdoor temperature readings to the indoor temperature monitor from up to 165 feet (50 meters) away We liked this feature because we didn’t have to consider what the numbers meant—the dial told us when it was a bit humid. We felt this was a handy function for those who wanted to see the comfort level at a glance. Young children could also probably understand the significance of the dial. Some indoor thermometers consist of a small sensor with no display; instead, data is sent to a compatible app on a smartphone. These compact indoor thermometers are ideal for monitoring the humidity or temperature in close quarters, such as a small humidor or a pet enclosure. Connectivity
Customer reviews
Though we couldn’t determine the exact degree of accuracy for all the thermometers tested, we did arrange them all side by side in the same location and then compared the readings. The AcuRite gave a near-identical reading to most of the other thermometers, so we concluded it was highly accurate.
