What is aura-meter?

An aura meter is a device used to measure and visualize the supposed energy fields or "auras" that surround living beings. It typically employs sensors to detect electromagnetic fields or biofields, translating these readings into visual representations, often in the form of colors or patterns. While some practitioners believe in its efficacy for spiritual or holistic purposes, scientific validation of aura meters remains limited, and their use is often considered pseudoscientific.
