Definition: “Ingress Protection” rating is the scale used to determine how protected a device is from dust and liquid ingress
Benefits (Why Bother?): The International Electrotechnical Commission (IEC) has created a standard for rating instruments based on their ability to protect their electronic components from corrosion by water or dust. The International Protection Rating code (or IP code) consists of the letters "IP" followed by two numbers. The first number tells you how protected an instrument's electronics are from penetration by solids (like dust) and the second number tells you how they stand up against liquids
