Abstract
A waterproofed environmental sensing device with water detection provisions includes an environmental sensor to sense one or more environmental properties. The device further includes an electronic integrated circuit implemented on a substrate and coupled to the environmental sensor via a wire bonding. An air-permeable cap structure is formed over the environmental sensor, and a protective layer is formed over the wire bonding to protect the wire bonding against damage.
Claims20
A device comprising:
- an environmental sensor configured to sense one or more environmental properties;
- an electronic integrated circuit implemented on a substrate and coupled to the environmental sensor via a wire bonding;
- an air-permeable cap structure formed over the environmental sensor;
