Abstract
A gas-sensing apparatus with gas convection capability includes a gas sensor mounted inside a container, a substrate forming a bottom plate of the container and an actuator. The gas sensor is mounted over a first surface of the substrate internal to the container. The actuator is coupled to a second surface of the substrate external to the container. The actuator can cause convection of a gas within the container by enabling movements of the substrate in response to an activation signal.
