Committed to providing high-precision, miniaturized spectral sensing products for innovative applications in consumer electronics, AIOT, and general industries, SEETRUM achieves chip-level spectral sensor, characterized by high integration and low cost. The response wavelength range extends from visible light to near-infrared. As a material fingerprint, the spectrum is an important information carrier for human understanding of the world. The spectral sensing products offer a new optical sensing solution that is online detectable, environmentally adaptable, and supports high-volume production for the detection and analysis of ambient or artificial light sources, colors, and substances. This supports further refinement in management, classification, quality control, and other applications. The spectral sensing series products provide multi-band optional sensor ICs, integrated module products, and related algorithms and software. These are suitable for portable, handheld, or miniaturized devices, enabling spectral sensing and analysis applications.
