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.

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 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. 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. We used the same standard for testing accuracy with humidity readings. In addition to being consistent, the AcuRite also stores high and low readings for 24 hours, showing us how much the temperature and humidity fluctuated.

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. 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. 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. 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. In addition to providing temperature data, most indoor thermometers also act as a humidity monitor. Some indoor thermometers can record high and low temperature and humidity readings over an extended period.Temperature Trend Arrows: The temperature gauge indoor outdoor lets you know whether the temperature is rising or falling 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. If you’re wondering how accurate an indoor thermometer and humidity gauge is or whether you can place your indoor thermometer outdoors, read on for answers to these and other questions about these devices. Q. What’s the difference between indoor thermometers and outdoor thermometers? Wireless Indoor Outdoor Thermometer: The easy-to-read LCD display, acting like an outdoor thermostat, provides current indoor and outdoor temperature with precision and accuracy 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
