    Magnetic Field Sensor: It detects magnetic fields around the device.

                        Near Field Communication (NFC) Sensor: It enables devices to share data when close together.

                        Orientation  Sensor: It detects  device  angle and direction,  used  in auto-rotate  screens,
                       AR apps and camera stabilisation.

                        Pedometer Sensor: It counts the steps you take while walking or running.
                        Proximity Sensor: It detects if an object is near the device without touching it.

                        Thermometer Sensor: It measures the temperature around the device.

                          ▶  The Location Sensor uses GPS to find the device’s position.
                          ▶  The Thermometer Sensor measures the temperature around the device.

                               CREATING AN APP USING SENSORS

                     Sensors can create apps that respond to movement, like a Pedometer app, which counts steps
                     using a pedometer sensor and displays the count on the screen.

                     DESIGNING THE USER INTERFACE (UI) FOR THE PEDOMETER APP

                     To design the user interface for the
                     Pedometer app, follow the given steps:

                     Step  1   Create new project in the MIT
                              App Inventor.

                     Step  2    Change the name of the screen
                              to  Pedometer in the  Title text

                              box, adjust  AlignHorizontal  to
                              Center:3  and  AlignVertical to
                              Center:2 in the Properties pane.
                     Step  3   Click on the User Interface

                              component.
