Important Considerations:
• Optimal performance of this app depends on the device's sensors. Accuracy of measurements is influenced by the hardware capabilities of your device.
• The app employs the built-in magnetic sensor of your phone, which may lead to certain limitations when achieving precise EMF readings.
• Factors such as the condition of your device and environmental variables can impact measurement outcomes.
• For high-grade EMF assessments, we suggest utilizing specialized apparatus.
Applicable Scenarios:
1. **Electromagnetic Research:** Measure electromagnetic data and record video, export CSV for analysis.
2. **Acoustic Work:** Measure decibels, monitor audio, and assist in sound effect tuning/audio production.
3. **Residential Inspection:** Check electromagnetic radiation from home appliances/environment, and trace the routing of electrical wires in walls.
4. **Paranormal Investigation:** Simultaneously measure electromagnetic/sound/vibration, and record abnormal data.
5. **DIY Creation:** Measure the electromagnetic radiation of homemade devices and adjust the volume of sound-producing works.
6. **Environmental Monitoring:** Long-term monitoring of the electromagnetic/sound environment of a region, storing data and analyzing trends.
7. **Nighttime Monitoring:** Enables dark mode to reduce glare, and continuously measures data in the background (can also be used with the screen locked).
Related Questions and Answers
1. Can ordinary users easily use this app to measure electromagnetic radiation without specialized knowledge?
Yes. The app features a simple and intuitive interface, with real-time graphs, clear numerical displays (microtesla, decibels), and professional-style dashboards. The results are easy to understand without having to understand complex principles. Basic calibration settings are also provided, and users can complete them by following the prompts, making it very user-friendly.
2. Can it measure electromagnetic radiation, sound, and vibration simultaneously? Do I need to switch modes each time?
It supports simultaneous measurement. The app has a "combined mode" that allows users to simultaneously obtain real-time data for electromagnetic radiation (EMF), sound decibels, and vibration, eliminating the need to repeatedly switch between function modules. This is ideal for scenarios that require simultaneous monitoring of multiple environmental parameters (for example, detecting the combined effects of electromagnetic radiation and noise in a specific area).
3. Can the measured data be exported for analysis, such as to compile reports on a computer?
Yes. The app's "Data Management" feature allows you to export measurement history in CSV format, which can be directly opened in office software like Excel and WPS. This makes it easy for users to organize data and create analysis reports. This feature is particularly useful for researchers conducting professional analysis or for casual users documenting environmental changes.
4. **Is there any way to reduce screen glare when using the phone in a dark environment? **
Yes. The app supports "Dark Mode." By enabling it in the settings, the interface switches to a dark background. This reduces screen glare in dark environments, protecting your eyes, and also reduces phone power consumption, making it ideal for long-term monitoring (for example, monitoring electromagnetic radiation in a specific area at night).
5. **Can the app continue measuring data if other apps are running in the background? **
Yes, the app can measure data in the background. The app has a "background measurement function" that allows users to continuously record electromagnetic radiation, sound, and other data even when switching to other apps or locking the screen. This eliminates the need to constantly stay in the app interface, allowing users to monitor and perform other tasks simultaneously.
