Abstract
A sensor assembly includes a housing, an air inlet tube through the housing and including a drain, and a sensor in the path of air flowing through the air inlet tube. The sensor assembly may further include a heater thermally connected to the drain. A controller may be communicatively coupled to the heater and programmed to activate the heater upon detecting an ambient temperature below a temperature threshold.
