Abstract

A gas sensor package is disclosed. The gas sensor package can include a housing defining a first chamber and a second chamber. An electrolyte can be provided in the first chamber. A gas inlet can provide fluid communication between the second chamber and the outside environs. The gas inlet can be configured to permit gas to enter the second chamber from the outside environs. An integrated device die can be mounted to the housing. The integrated device die can comprise a sensing element configured to detect the gas. The integrated device die can have a first side exposed to the first chamber and a second side exposed to the second chamber, with the first side opposite the second side.
