1. A sensor unit configured to be affixed to an object, the sensor unit comprising:
a light sensor configured to measure light intensity;
an angle sensor configured to measure angle relative to a reference vector; and
a processor configured to:
determine that if the light sensor measures light intensity greater than a threshold value, the object is out of a container; and
determine that if the light sensor measures light intensity less than a threshold value and the angle sensor measures an angle within a particular range of values relative to the reference vector, the object is in the container, wherein the processor is configured to check the angle measured by the angle sensor only after determining that the light intensity measured by the light sensor is less than the threshold value.
