Compound Hound Teaches Machines to Smell

Field notes

Compound Hound describes a solid-state sensing device that records a full spectral fingerprint rather than a single aggregate reading. The homepage separates its approach into three features: richer spectra, avoidance of added surface chemistry, and software-based reconfiguration. It claims that new detection applications require a model change rather than a hardware redesign, while offering no public datasets, example readings, performance benchmarks, or technical documentation.
