What does sensors off do on Android?

When Sensors off is enabled, the sensors stop reporting any data to the system or apps. An app can still request a sensor and register a listener when Sensors off is enabled, but either silence is returned for the mic or the onSensorChanged callback is never invoked for the sensors.

What is an example of a sensor?

The simplest example of a sensor is an LDR or a Light Dependent Resistor. It is a device, whose resistance varies according to intensity of light it is subjected to. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the LDR becomes very high.
