Scalp sensing device and scalp analysis system including the same

A portable scalp sensing device comprising:

• a camera module comprising a camera part including an image sensor and a lens, a light diffusion member disposed on an optical axis of the camera part, a blue-cut filter disposed between the camera part and the light diffusion member to block light of a predetermined wavelength that is incident on the camera part, a UV light source, and at least one white light source;
• a scalp environment sensor;
• and
• an upper casing configured to cover the camera module and the scalp environment sensor, wherein the light diffusion member is configured to diffuse and guide light emitted from each of the at least one white light source and the UV light source to direct the light onto a measurement target region,
• wherein the camera part is configured to capture an image of the measurement target region illuminated by the light,
• wherein the scalp environment sensor includes one or more of a temperature sensor, a moisture sensor, and a volatile organic compound (VOC) sensor fixed onto the support plate, the camera module is disposed adjacent to the scalp environment sensor,
• the upper casing includes a camera part cap configured to tightly cover an upper portion of the light diffusion member disposed on an upper end of the camera part and an environment sensor cap configured to cover the scalp environment sensor, and
• a plurality of through-holes are formed in the environment sensor cap.

A portable scalp sensing device comprising:
