Abstract
A dual sensor module includes a substrate, a light source, a first encapsulant, a second encapsulant, a photodetector, and an electrode. The light source is disposed on the substrate. The first encapsulant is formed over the light source. The photodetector is disposed on the substrate. The second encapsulant is formed over the photodetector. The electrode is electrically connected to the substrate and is entirely located between the light source and the photodetector. A dual sensing accessory and a dual sensing device having the dual sensor module for detecting optical and electrical properties are also provided.
