A light sensor assembly includes a sensor connector configured to be coupled to a receptacle connector mounted to a light fixture. The sensor connector includes a housing having a top and a bottom defining a mating interface configured to be mated to the receptacle connector. The housing has a sealed cavity including a first sensor component in the sealed cavity sensing an environmental characteristic exterior of the sensor connector. The sensor connector includes power contacts held by the housing and extending from the bottom for electrical connection with receptacle power contacts of the receptacle connector. The sensor connector includes a lid assembly at the top of the housing. The lid assembly has a lid defining an unsealed cavity allowing airflow through the unsealed cavity. The lid assembly has a second sensor component in the unsealed cavity sensing an environmental characteristic exterior of the sensor connector.
