1. A sensor, the sensor comprising:
a housing, wherein the housing comprises a rim defining a first infrared prism cavity and a second infrared prism cavity, wherein the housing further comprises a slit mount defining a slit mount cavity, wherein the slit mount is disposed between the first infrared prism cavity and the second infrared prism cavity;
an infrared light emitter located proximate the first infrared prism cavity of the housing; and
a microprism disposed within the slit mount,
wherein the microprism is configured to refract a first electromagnetic wave emitted from the infrared light emitter, wherein the first electromagnetic wave traverses the first infrared prism cavity to the second infrared prism cavity via the microprism.
