Ingress Protection Rating

The IP code consists of two digits: the first rates protection against solid foreign objects and dust, the second against water ingress. IP54 means dust-protected with protection against splashing water from any direction. For agricultural drones, IP54 is the practical baseline because spray nozzles and mist saturate the airframe during operation. Higher ratings such as IP65 or IP67 matter for inspection work in rain or coastal environments. The rating applies to the assembled aircraft in its operating configuration, not to individual components.
