Abstract: Example embodiments of the present disclosure provide an optical module sensor. An example optical module sensor may include an optical radiation-emitting device, a reference, an optical radiation receiver positioned, an electromagnetic interference shield, and a housing cap. The housing cap may include a barrier wall positioned such that the housing cap defines a transmission cavity and a receiving cavity. The optical radiation-emitting device and the reference sensor may be positioned within the transmission cavity and the optical radiation receiver may be positioned within the receiving cavity. The housing cap may include an attenuation wall positioned between the reference sensor and the optical radiation receiver.
