The register method of sensor in this preferred embodiment comprising:
Step S201: the sensor list of hardware abstraction layer is obtained, wherein the sensor list includes multiple sensors
The information of type；
In booting, the operating system of terminal will register sensor terminal.During registration, ccf layer is needed
Obtain the sensor list in hardware abstraction layer, wherein sensor list includes multiple sensor types, here multiple sensings
Device type refers at least one sensor type.It should be noted that driving layer can setting according to operating system when terminal booting
Set addition sensor environment variable.Hardware abstraction layer reads sensor environment variable from driving layer, and according to the sensor ring
Border variable generates corresponding sensor type, and saves into sensor list.
Step S202: access driving layer, and judge in the driving layer with the presence or absence of corresponding with the sensor type
