Smartphones can do anything.
Portable music players, diary books, digital cameras, calculators, and devices that were carried separately 20 years ago are now available for one smartphone.But in fact, there may not be so many major functions that can measure various things with smartphones.If you have an appropriate sensor and an appropriate app, you can actually measure more data than expected.This time, let's introduce what can be measured with a smartphone.
Measure altitude
If the smartphone you are using is equipped with a GPS signal, map, and a pressure sensor (now in most smartphones), the smartphone will be an altimeter right now.To check the altitude, you need to install a third -party app.
For iOS, we recommend My Altitude or My Altitude and Elevation GPS app.For Android, My Elevation or Altimeter Ler is recommended (if you want accuracy, try it several times and check if it matches).These four apps are all free (some have in -app purchases).Also, check out the high altitude apps, such as running, cycling, skiing, etc., can be measured.
Measure humidity
At present, the smartphone does not have a hygrometer (humidity sensor).If you want to know the humidity, you may want to use an app that takes online and teaches the humidity outside the area where you live.Or you need to buy a gadget that can actually measure the humidity and synchronize the results to your smartphone.
For iOS, there is a free "humidity meter" app, and for Android, there is a "real -time thermometer humidity meter" app, but most of the weather apps can be found.
In addition, gadgets that measure indoor and outdoor humidity are $ 180 (about 19,700 yen) Netatmo Weather Station, one of the optimal options, and even more affordable, $ 55 (about 6,000 yen) GOVEE THERMO-HYGROMEter.there is.If it is made in Japan, the smart remote control Nature Remo has a humidity sensor, so it is possible to control the air conditioner on and off depending on the humidity.
Measure the distance
Fitness apps such as Google Fit and Apple Health measure the distance when moving, but if you want to measure the distance from point A to point B, free Strava app (iOS version, Android version).Is one of the optimal options.You can record how far the distance you have moved and plot on the map.
In addition, there are many other applications that can measure the distance.MILEIQ (free, but not provided in Japan) tracks the mileage of the car, and Polarsteps (free of charge) records how far the land, the sea, and the sky have moved.
If you do not move and want to measure the distance only on the app, you can measure it with the Google Map App.Press and hold the map, drop the red pin, swipe the "specified point" up, and select "Measurement of distance".
Measure speed
The smartphone is equipped with an accelerometer and other built -in sensors, especially the speed measurement function.Even the familiar Google map shows the speed while driving.Cyclemeter (iOS version, Android version) for cyclists is well made, and various data, including speed, is measured and displayed in real -time while running.
If you want to look only at the speed, SPEEDVIEW in Android, SPEEDOMETER SPEED BOX APP (both free) for iOS is the most useful app (this category has many various apps).In both cases, you can measure and check the speed accompanying the passage of time in the graph.SPEEDVIEW can also export data.
Examine air pollution
Like humidity, smartphones do not have the required sensor to measure the air quality index.However, there are apps that inform the current air quality index in the residential area.AIRVISUAL (iOS version, Android version, free), which provides more than 10,000 cities and weather data in cities around the world, provides a lot of statistical information and real -time information.AIR Matters (iOS version, Android version) is also recommended.
Another method is to purchase an indoor air quality index that can send the atmosphere to a smartphone (usually displays that information on the built -in display).The two major options here include $ 185 (about 20,000 yen) AirTHINGS WAVE PLUS and AWAIR with a retro appearance of $ 170 (about 18,700 yen).These gadgets also support Alexa and Google Assistant.
Measure dimensions and area
Both Google and Apple have released genuine major (measurement) apps and use the expansion reality (AR) to change their devices into major (rolls).You can measure the size of the object, automatically detect the dimensions of the square object, and measure the floor area.The value measured in AR is not perfect, but it is useful to judge the size and dimensions of the approximate space.
The ruler (RULER) and Moasure (Smart Tape Major) apps are useful on Android.In iOS, Ruler (combining AR and non -AR measurement tools) is also recommended.
Measure the weight
Smartphones are not a substitute for scale.In the first place, if you get on your smartphone, your smartphone will break into it.
However, if you are a small object, try Android Working Scale, which can measure the mass (or weight) placed on it.You can measure about 2 grams to 100 grams.
If you want to manage your weight on your smartphone, buy a smart scale.Many smart weight meters have been released from Fitbit ARIA for about 14,000 yen, and Tanita and Omron in Japan.
