IP00 vs IP01
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP01 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 1). IP00 is rated for no protection and no protection, while IP01 provides no protection and vertically dripping water.
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
IP01 provides no protection against solid objects and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 1.

The exact difference (IP00 vs IP01)
Solid protection
IP00
Level 0 — No Protection
IP01
Level 0 — No Protection
Both IP00 and IP01 share the same solid protection: No Protection.
Liquid protection
IP00
Level 0 — No Protection
IP01
Level 1 — Vertically Dripping Water
IP00 provides "No Protection" (level 0), while IP01 provides "Vertically Dripping Water" (level 1). IP01 is 1 level higher.

Recommendation
IP01 offers higher overall protection than IP00. Choose IP01 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
