Introduction to sensor types in Android

Speaking of sensors, we are more familiar with the gravity sensor and light sensor of the mobile phone. Because many of us sense the rotation of the mobile phone, and the screen goes off when close to the ear when making a call, these are all due to the sensor. Today I will introduce the types of sensors in Android and explain how to obtain the sensors supported by the current mobile phone.

1. Types of sensors in Android

serial number	Sensor type of Sensor	Sensor name	Description
1	TYPE_ACCELEROMETER	Acceleration	Often used for shake function
2	TYPE_MAGNETIC_FIELD	magnetic field
3	TYPE_ORIENTATION	direction	Deprecated, replaced by getOrientation method
4	TYPE_GYROSCOPE	Gyro	Used to sense the rotation and tilt of the phone
5	TYPE_LIGHT	Light	Used to sense the intensity of the light on the front of the phone
6	TYPE_PRESSURE	pressure	Used to sense air pressure
7	TYPE_TEMPERATURE	temperature	Deprecated, replaced by type 13
8	TYPE_PROXIMITY	distance
9	TYPE_GRAVITY	gravity
10	TYPE_LINEAR_ACCELERATION	Linear acceleration
11	TYPE_ROTATION_VECTOR	Rotation vector
12	TYPE_RELATIVE_HUMIDITY	Relative humidity
13	TYPE_AMBIENT_TEMPERATURE	Ambient temperature
14	TYPE_MAGNETIC_FIELD_UNCALIBRATED	No calibrated magnetic field
15	TYPE_GAME_ROTATION_VECTOR	Uncalibrated rotation vector
16	TYPE_GYROSCOPE_UNCALIBRATED	Uncalibrated gyroscope
17	TYPE_SIGNIFICANT_MOTION	Special action
18	TYPE_STEP_DETECTOR	Walk detection	An event is triggered every time the user takes a step
19	TYPE_STEP_COUNTER	Walk count	Record the number of steps after activation
20	TYPE_GEOMAGNETIC_ROTATION_VECTOR	Geomagnetic rotation vector
21	TYPE_HEART_RATE	Heart rate	Use of wearable devices, such as bracelets
22	TYPE_TILT_DETECTOR	Tilt detection
23	TYPE_WAKE_GESTURE	Wake up gesture
24	TYPE_GLANCE_GESTURE	Swipe gesture
25	TYPE_PICK_UP_GESTURE	Pick up gesture
