## Abstract

The present invention relates to an adaptable sensor assembly to be mounted to a light fixture in a fixture opening of the light fixture. A mount extends from the sensor housing. A break point is defined in the mount. First and second mount portions are located on either side of the break point. Each of the first and second mount portions are able to connect to the light fixture at the fixture opening. The first mount portion may connect to the light fixture if the light fixture has a large gasket lip, and the second portion may connect to the light fixture if the light fixture has a short gasket lip.

## Claims

### Claim 1

A method of mounting a sensor assembly on a corresponding light fixture having a fixture opening defined therein, the method comprising:
for a first light fixture having a gasket lip extending adjacent to a sensing area of the sensor assembly when the sensor assembly is mounted on the first light fixture without a spacer:
(a) detaching a first mount portion from a second mount portion collinear with the first mount portion at a break point defined between the first mount portion and the second mount portion; and
(b) removably connecting the sensor assembly to the light fixture by inserting the second mount portion into the fixture opening; and
for a second light fixture having a gasket lip extending into the sensing area of the sensor assembly when the sensor assembly is mounted on the second light fixture without the spacer:
(c) placing the spacer that is longer than the second mount portion onto the sensor assembly such that at least some of the first mount portion extends beyond the spacer; and
(d) removably connecting the sensor assembly to the light fixture by inserting the first mount portion into the fixture opening.

### Claim 2 (depends on 1)

The method of claim 1, wherein the break point is structurally weaker than the first mount portion and the second mount portion.

### Claim 3 (depends on 1)

The method of claim 1, wherein:
step (b) further includes threading the second mount portion into a fixture opening of the first light fixture; and
step (d) further includes threading the first mount portion into a fixture opening of the second light fixture.

### Claim 4 (depends on 3)

The method of claim 3, wherein step (c) further includes threading the spacer onto at least one of the first mount portion or the second mount portion.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
for the first light fixture having the gasket lip that extends adjacent to the sensing area of the sensor assembly when the sensor assembly is mounted on the first light fixture without the spacer, placing a gasket between a sensor housing of the sensor assembly and the first light fixture; and
for the second light fixture having the gasket lip that extends into the sensing area of the sensor assembly when the sensor assembly is mounted on the second light fixture without the spacer, placing the gasket between the spacer and the second light fixture.

### Claim 6 (depends on 1)

The method of claim 1, wherein step (c) includes removably connecting the spacer to at least one of the first mount portion, the second mount portion, or a sensor housing of the sensor assembly.
