A sensor is provided for determining at least one parameter of a fluid medium flowing through a measurement channel, in particular an intake air mass flow of an internal combustion engine. The sensor has a sensor housing, in particular a plug-in sensor that is inserted into or is insertable into a flow tube, in which sensor a measurement channel is fashioned, and has at least one sensor chip situated in the measurement channel for determining the parameter of the fluid medium. The sensor housing has an electronics compartment for accommodating an electronics module and has an electronics compartment cover for closing the electronics compartment. The electronics compartment cover has, at least in part, electrically conductive properties. For example, the electronics compartment cover is placed onto the electrical ground of the sensor and, viewed in projection, partly or completely covers the sensor chip.
