SMD-enabled infrared thermopile sensor

An SMD-enabled thermopile infrared sensor for contactless temperature measurement, as a hotspot, or for gesture detection,

• having at least one thermopile pixel on a monolithic integrated sensor chip, which is arranged in a hermetically sealed housing, which consists of an at least partially nonmetallic housing substrate and a housing cover,
• wherein a gas or gas mixture is located in the housing,
• wherein an aperture opening (26) is introduced into the housing cover (3) opposite to the at least one thermopile pixel (29), which opening is closed using a focusing lens (4), which focuses radiation of objects onto the at least one thermopile pixel (29) on the housing substrate (1),
• wherein the housing substrate (1) consists of an insulator, which is provided with a recess (30) and side walls (31) for accommodating the sensor chip (2),
• wherein the housing cover (3) has angled lateral edges (32), which are supported hermetically sealed on the side walls (31) of the housing substrate (1),
• wherein the housing substrate (1) has metallic connections (9) from a front side to a rear side, which are provided on the rear side of the housing substrate (1) with contact surfaces (10) for a surface mounting,
• wherein a signal processing unit (12) is integrated on the sensor chip (2) adjacent to the at least one thermopile pixel (29), and
• wherein an overall height of the housing is at most 3 mm.
