Android Lux Meter: How to Measure Light Intensity with Your Android Device
A lux meter is a tool used to measure the intensity of light in a particular area. This measurement is essential in various fields such as photography, interior design, and workplace safety. While traditional lux meters can be expensive, modern smartphones offer a more convenient alternative. Thanks to the sensors embedded in Android devices, it’s possible to measure light intensity directly from your phone using a lux meter app.
In this article, we will explore what a lux meter is, how it works on Android devices, and recommend some popular Android apps that turn your phone into a lux meter.
What is a Lux Meter?
A lux meter is a device used to measure illuminance, which refers to the amount of light that falls on a surface. The unit of measurement for light intensity is lux (lx), which represents one lumen per square meter. Lux meters are commonly used in various fields such as:
- Photography: To determine the right lighting for taking photos.
- Building design: To ensure rooms are well-lit and meet lighting standards.
- Workplace safety: To measure whether a workspace has sufficient light for employees to work safely.
- Agriculture: To monitor light conditions for growing plants.
Lux meters are useful when you want to know the exact amount of light in a specific area, especially if you’re testing or adjusting lighting for any of the applications mentioned above.
How Do Android Lux Meter Apps Work?
Most Android phones come equipped with a light sensor, which is typically used to adjust the brightness of your screen depending on your environment. This sensor detects the amount of ambient light surrounding the device and can be used to measure lux. Lux meter apps tap into this sensor to display the intensity of the light in real-time.
While these apps are not as precise as professional equipment, they can give you a good estimate of the light intensity. The light sensor on Android devices typically measures the ambient light level (lux) and converts it into readable data.

How to Use an Android Lux Meter App
Using a lux meter app on your Android phone is easy. Here’s a simple step-by-step guide to measuring light intensity with your phone:
-
Download a Lux Meter App: Choose one of the apps mentioned above and download it from the Google Play Store.
-
Calibrate Your Device (Optional): Some apps may require calibration before use. You can usually find the calibration option in the settings of the app. Follow the instructions provided in the app to calibrate the sensor for more accurate results.
-
Select the Measurement Mode: Some apps offer multiple modes, such as spot measurement or ambient light measurement. Select the mode that suits your needs.

Hold the Phone in the Desired Location: Point your Android device’s light sensor towards the area you want to measure. Ensure the sensor is not blocked by your hand or case.
-
Read the Measurement: The app will provide a reading in lux (lx), which is the standard unit for measuring light intensity. Some apps also allow you to view the data in foot-candles (fc), which is commonly used in the United States.
-
Take Notes or Save the Reading: If you need to compare readings, some apps allow you to save or record your measurements for later reference.
Limitations of Android Lux Meter Apps
While Android lux meter apps can be very helpful for basic light measurements, there are some limitations to keep in mind:
-
Accuracy: The accuracy of light measurement will depend on the quality of your device’s light sensor. Most smartphone sensors are not designed to provide highly accurate lux readings, so the readings may not be as precise as professional-grade lux meters.
-
Environmental Factors: The presence of a case, screen protector, or other obstructions can impact the sensor’s ability to measure light accurately. For the best results, ensure that the sensor is unobstructed when taking measurements.
-
Sensor Calibration: Not all devices have highly calibrated light sensors, so the app may need manual calibration to provide more reliable readings. Without proper calibration, the readings may not reflect the actual light intensity.
Applications of Android Lux Meter Apps
There are many practical applications for using a lux meter app on your Android device, including:
