App Description
Detect EMF & radiation using phone's magnetic sensor.
EMF Detector – Detect Electromagnetic Fields with Your Smartphone! 📡
Do you ever wonder if there are invisible electromagnetic fields (EMF) around you? Want to detect hidden EMF signals with ease? This app turns your Android phone into a powerful electromagnetic field detector using your device’s built-in magnetic sensor. ⚡📲
📌 Key Features of EMF Detector:
----------------------------------
🔸 Real-time EMF detection
🔸 Digital and analog meter display
🔸 Graph view for live data
🔸 Sound alerts for strong EMF
🔸 Adjustable sensitivity
🔸 EMF scanner calibration
🔸 Works offline & with dark mode
📡 How It Works:
------------------
Your phone's magnetic sensor detects changes in the electromagnetic field around it. These readings are converted into visual and audio indicators inside the app. The results are shown in microTesla (µT), the standard unit for magnetic fields.
📏 Detection Range:
----------------------
The range depends on your phone's hardware. On average:
• 📲 Detection range: 15cm–25cm
• 📉 Sensitivity: Based on your magnetic sensor strength
• ✅ Works best with devices having a built-in magnetometer
📲 EMF Measurement Modes:
-----------------------------
• Meter View: Classic needle gauge
• Graph View: Live signal fluctuations
• Digital View: Exact µT values
• Calibration: Customize for accurate detection
• Sound Alerts: Audio feedback on EMF spikes
🔎 Use Cases:
-----------------
• Detect hidden EMF signals
• Locate electrical wiring behind walls
• Test your environment for EMF radiation
• Educational tool for students & science lovers
• Quick EMF scanner for engineers & researchers
🚫 NOTE:
----------
This app requires a magnetic sensor (magnetometer) to function. 📴 If your device does not support this hardware, the app will not work. Try using another smartphone with a built-in magnetic sensor.
🛠️ Calibration & Accuracy:
------------------------------
We provide manual calibration tools to help you set the app based on your environment and improve accuracy. Different phone models may show slightly varied readings due to sensor quality.
🔋 Lightweight & Battery-Friendly:
-------------------------------------
This EMF scanner is optimized for low power consumption, so you can keep it running during surveys or exploration without draining your battery quickly. 🔋📉
🕵️ Who Can Use This App?
-----------------------------
• Engineers checking EMF hotspots
• People concerned about EMF pollution
• Hobbyists exploring magnetic fields
• Students studying electromagnetic waves
• Homeowners locating electric wiring behind walls
💬 Disclaimer:
----------------
This app is designed for detection of electromagnetic fields only. It is not a professional scientific tool, but it can be used for educational and general detection purposes. The accuracy is dependent on the quality of the sensor in your mobile phone.
