Best Wireless Humidity Sensor & Thermometer (WiFi Hygrometer)

Best Wireless Humidity Sensor & Thermometer (WiFi Hygrometer)

A hygrometer is a humidity sensor or meter that can be used to measure the amount of water vapor in the air.

It is a relative number to the maximum level of water the air can hold. So, when it rains that is close to 100% humidity.

With a wireless humidity sensor, one that has Wi-Fi, you can monitor the humidity from a remote location.

Uses of a Wireless Humidity Sensor

Since temperature and humidity are closely linked, it makes sense to provide temperature data along with humidity data.

Why not have just 1 small sensor that integrates WiFi, so you can deploy the temperature and humidity sensor and get the data automatically without having to disturb the air around the sensor.

For example, monitor the humidity inside a guitar case without having to open the guitar case just to check the digital reading. Just open the app on your phone.

Scientific & Industrial

There are many uses for hygrometers in scientific and industrial applications.

For example, monitor ambient humidity to ensure compliance with testing standards when curing specimens, such as concrete bars, mortars, cement pastes.

Keeping the ideal temperature and humidity can be critical when performing certain chemical measurements and mixes.

Closely track ambient conditions on experiments for reliable data and identifying chemical or water leaks in scientific chambers

A reliable hygrometer humidity sensor can be used as your “working instrument”. You can reference it against your calibrated hygrometer. This allows you to keep an eye on the expensive calibrated equipment to know when it is out of spec and should be re-calibrated.

Monitor Server Room Temperature & Humidity

Do you have a server room or computer equipment that needs to be monitored?

Most electronic equipment needs to operate within a temperature and humidity range, particularly computer equipment, routers, and servers.

Having a server room thermometer and humidity sensor that can alert you if either temperature or humidity falls out of range can be a huge advantage to taking corrective action quickly.

Perhaps the power has gone out in the equipment room. You can get alerts if power is lost/restored.

We have one of the few temperature and humidity sensors that has a dedicated power connection and Wi-Fi so you don’t have to worry about changing batteries.

WiFi Humidity Sensor for a Humidor

It is best to measure the humidity and temperature in a box without having to open it to see the readings.

For this reason, a WiFi humidity sensor works best since you only need to look at your phone to see the current values.

The same principle applies to guitar or violin cases, incubators, reptile cages, greenhouses, etc.

Home & Safety

There are many things that need to stay in a particular humidity range to stay safe at home. Examples such as guitar cases, greenhouse, cigar boxes, a humidor, or even remotely monitor your vacation home.

Also, a wireless humidity sensor is great at detecting possible water leaks. You could put one in a room like a basement or crawl space and monitor the normal humidity levels over time.

Looking at the humidity graph you may notice it is gradually trending higher, maybe after lots of rain or bad weather.
This might indicate a possible water leak in that room.

Bedroom or Baby Room Monitor

Temperatures between 65 – 70 and humidity levels around 40% are ideal for sleeping. This is also the best temperature for a sleeping baby.

With a baby room temperature sensor you can monitor the ideal temperature and humidity levels.

Attic & Crawl Space Moisture Sensor

You should monitor your attic for excessive moisture levels. This can tell you if there is a leak in the roof or improper ventilation leading to mold and rafter damage.

This can be done with the Trakkit THS Temperature Humidity Sensor.

Health Effects of Temperature & Humidity

Maintaining temperature and humidity in your home or office can have several health benefits. High humidity can have bad effects on many things in your home, not just your health.

Ideal Indoor Humidity

Proper temperature and humidity in your house can prevent health issues and long term damage to your house.

A Relative Humidity range of 30% – 55% is ideal.

Preventing high moisture levels will reduce possible mold and fungi problems that can affect allergies, sinus, and respiratory issues.

Healthy Humidity Levels

See the chart below:

For example, cooler air is better when sleeping for maximum oxygen intake, cooler, denser air. It will also help you sleep better.

Now that many of us are spending more time at home due to the outbreak of the coronavirus pandemic, making sure that we are comfortable and safe is crucial. It may not seem like it a first, but temperature and humidity play a huge factor when it comes to these two factors.

In fact, research emphasizes that cold and dry air may increase the transmissibility of coronavirus. Ideally, having humidity levels of between 30-60% in your home is best to contain the impacts of the virus.

In addition to hand washing and social distancing, investing in a humidifier during the winter season might come in handy.

How to Improve Air Quality at Home

In addition to the possible transmission of viral illnesses, indoor air can be dirtier than we are often lead to believe. In fact, it can often be two to five times more polluted than outdoor air.

Common pollutants include air fresheners, pesticides, asbestos, mold, and tobacco smoke. If you live near a busy road, outdoor pollutants can also enter your home and affect your indoor air quality.

Some short-term effects of poor air quality include dryness and irritation to facial features, fatigue, shortness of breath, allergies, sinus congestion, coughing, and sneezing.

These side effects are also associated with less than optimal temperature and humidity levels. Furthermore, long-term effects can include a worsening of respiratory illness such as asthma and bronchitis.

To prevent this, investing in an air purifier and allowing fresh air to enter the house will help boost circulation. Lastly, you can try and eliminate individual sources of pollution like gas stoves or reduce their emissions.

Temperature & Humidity Graphs Show Trends

It is important to be able to see graphs for each of the Humidity and Temperature levels and the times they occurred.

This allows you to see trends and high and low extremes that you may not be aware of without a graph.

With integrated WiFi inside the sensor, you can have the data automatically uploaded to the cloud to trigger alerts, graph, or analyze later.

Our Trakkit THS – WiFi Hygrometer contains an integrated heater to keep the sensor clean and extend reliability. This heater can be user-activated from the phone app.
