There wasn’t much to complain about with the AcuRite hygrometer. The only real downsides were that it doesn’t come with instructions, so you’ll have to play around with it a bit to figure out how to use all of its functions. Plus, the magnet can slip off your fridge easily since it’s attached to the clip, not the hygrometer itself.
We’ve researched the best hygrometer available today, so we can offer you our recommendations on which one to pick. Don’t forget that if you like our hygrometer app, you can rate it and comment on how satisfied you are with other users. A pioneering recommendation platform where you can research, discover, buy, and learn how to connect and optimize smart devices. Google said in October 2019 that in 2020 it would create a system called Home Routines, as a way for smart home devices to talk to, and give instructions to Google Nest products.
Thermometer - Hygrometer
Connect an unlimited number of sensors to monitor multiple locations within one account. With Google Home, your Nest and Works with Google Home devices work together reliably to help with your household needs. Just look for smart devices with a Works with Google Home badge.

Customize your devices to do what you want, when you want, with new automations in the Google Home app. Moisture created by a kitchen or bathroom can throw off the readings, so it’s best to keep your hygrometer in a dryer space like a living room or office. If you still have some questions about your hygrometer, don’t sweat it.
Mechanical Hygrometers
All of this does come at a cost, however, as this model is fairly expensive. They display the humidity readings in larger print than the temperature reading, allowing users to see the crucial value first. They are accurate within 5 percent humidity and 2 degrees Fahrenheit. Each hygrometer uses one 1.5-volt LR44 battery that is easy to replace. Just keep in mind that these are not smart sensors, so users will have to open their instrument cases to check them.

Psychrometers use two types of thermometers to measure the air’s moisture content. It’s a rather complicated process that involves wrapping one of the thermometers in a wet cloth and spinning both thermometers. The experimenter then enters the readings from the thermometers into an equation to determine the humidity level.
Better camera and timeline views.
For instance, monitoring a wine cellar or cigar humidor’s humidity level can be the difference between maintaining a wonderful selection or spoiling an expensive collection. A highly beneficial function with some of the best hygrometers is remote monitoring and alerts. In other words, you can monitor your device remotely from an app, and receive alerts if levels exceed your pre-set limits. Our top choice, the Temp Stick, has WiFi connectivity to deliver these remote capabilities.

Matter devices connect to each other locally over your smart home network using Wi-Fi or Thread, making your devices more responsive, reliable, and secure. With Google Home, easily create helpful automations with your devices. Schedule your cameras to turn on and your doors to automatically lock at sunset. The totally redesigned app has a new five-tab layout that’s easier to navigate. Pin your favorite devices to your home view to see multiple camera live streams right when you open the app. The Bob Vila team distills need-to-know information into project tutorials, maintenance guides, tool 101s, and more.
Moisture condenses on the polished-metal mirrors of dew-point hygrometers. By noting the air temperature at which water begins to condense on the mirror, experimenters can determine the dew point. These devices require extremely consistent conditions, including constant atmospheric pressure and constant vapor content, to provide accurate readings. Electrical hygrometers are the most widely used hygrometers available today, and the most high-tech.
In addition I have an older ThermoPro indoor/outdoor and two Honeywell thermostats that display RH. Discounting the Honeywell downstairs, I had five near each other and compared. Those are the old indoor/outdoor, the two AcuRites, the Thermopro TP50, and the upstairs Honeywell.
For instance, you can place sensors in your attic, humidor, basement, storage room, wine cellar, outside, or other indoor areas, to monitor all of them at once. One of the most popular uses for hygrometers is for cigar enthusiasts. In order to keep cigars fresh, you have to ensure they are stored properly. Cigar enthusiasts will buy a wooden box called a cigar humidor to store their cigars in.

Each sensor can also be monitored by an unlimited number of users. Users report that setup is easy, and the sensor runs on a CR2477 coin cell battery , providing over a year of battery life. In addition, the Swiss-made sensing component in the SensorPush ensures reliable, accurate measurements. It also can send text or email alerts if the humidity or temperature gets too high or low.
In fact, numerous studies have demonstrated that relative humidity can have a profound effect on a variety of health issues. For people whose doctors have recommended a controlled-humidity environment, whether lowering or raising the humidity, measuring humidity can be particularly critical. If you’re interested in monitoring multiple locations within your home, including indoors and outdoors, we recommend the Ambient Weather WS-10 Wireless Thermo-Hygrometer.
I think the digital displays imply a level of accuracy that doesn’t exist unless you have hundreds or maybe thousands to spend. Probably the best accuracy these should display is very dry – dry – moderately dry – optimum – moderately humid, – humid – very humid. I just had an Aprilaire dehumidifier installed to try to get a handle on what my A/C leaves behind in the air.
Remote Monitoring and Alerts
If you’re looking for something a little more “vintage”, then you’ll want to consider the Cigar Oasis Analog Hygrometer by Western Humidor. This is one of the best analog hygrometers on the market today. It’s a great mechanically-operated hygrometer that was specifically designed to preserve cigars.
