The Spirit Music Box works similar to the world famous Para4ce device, but this app uses a lot more sensors! Most physical ghost hunting hardware uses a type of sensor and most of these sensors are built in to mobile devices. If any of the sensors pick up a change then the Music Box will start playing an old eerie music box song. A great tool to have with you on a Ghost Hunt or Paranormal Investigation! Simply place the device in any area, click the "Calibrate" button then move away from the device. If you move the device after it has been calibrated you will need to recalibrate, simply click the "Back" button, move the device to a new area, then click "Calibrate" again. If any of the sensors are too sensitive and are picking up noise (generating false positives), you can turn the sensor off by clicking on the sensor box on the screen. The sensors used are: EMF - This uses the magnetometer sensor for Magnetic and Electromagnet fields around the device MOVEMENT - This uses the Accelerometer, Gyroscope, Linear Accelerometer and Gravity sensors to detect any device movement and the slightest vibrations around the device PROXIMITY - Can detect if something moves close to the device LIGHT - Detects any changes in light around the device AIR PRESSURE - Detects any change in the Ambient Air Pressure around the device TEMPERATURE - Detects any changes in the Ambient Temperature around the device HUMIDITY - Detects any changes to the Humidity around the device DEW POINT / R-HUMID - This uses the Relative Humidity sensor to detect any moisture around the device. If the temperature sensor is also present then by using both the temperature and relative humidity sensors we can work out the dew point. Please check what sensors your device has. The app will still work without them, using the sensors that your device has got. If your device is missing any sensors then it will state "Sensor not found" in the sensor box. After many years of Researching sensor data for lots of different types of paranormal apps, I have concluded that the best way for Spirits to manipulate a device (or the device sensors) is by keeping it simple and universal across the whole world.
