IP Waterproof Ratings for Outdoor Smart Tech Explained

When it comes to outdoor smart technology, ensuring that your devices can withstand the elements is crucial. This is where IP (Ingress Protection) ratings come into play. These ratings provide a clear indication of how well a device is protected against dust and water, making it easier for consumers to choose the right products for their needs.

What is an IP Rating?

An IP rating consists of two digits, each representing a different type of protection. The first digit indicates the level of protection against solid particles, such as dust, while the second digit denotes the level of protection against liquids, such as water. The higher the number, the greater the protection.

Breakdown of IP Ratings

Here’s a detailed breakdown of what each digit in an IP rating represents:

First Digit: Solid Particle Protection

0: No protection
1: Protection against objects larger than 50mm (e.g., hands)
2: Protection against objects larger than 12.5mm (e.g., fingers)
3: Protection against objects larger than 2.5mm (e.g., tools, wires)
4: Protection against objects larger than 1mm (e.g., small wires)
5: Limited protection against dust (dust may enter but won’t affect operation)
6: Complete protection against dust

Second Digit: Liquid Ingress Protection

0: No protection
1: Protection against vertically dripping water
2: Protection against dripping water when tilted up to 15 degrees
3: Protection against sprayed water at angles up to 60 degrees
4: Protection against splashing water from any direction
5: Protection against low water pressure from any direction
6: Protection against powerful water jets
7: Protection against immersion in water up to 1 meter for 30 minutes
8: Protection against continuous immersion in water beyond 1 meter (manufacturer specifies depth)
9K: Protection against high-pressure, high-temperature water jets (typically for industrial use)

Common IP Ratings for Outdoor Smart Tech

When selecting outdoor smart technology, it’s essential to choose devices with appropriate IP ratings to ensure they can withstand the conditions they’ll be exposed to. Here are some common IP ratings and their applications:

IP44: Suitable for outdoor lights and speakers in partially enclosed areas. Provides protection against splashing water and solid objects larger than 1mm.
IP65: Ideal for outdoor cameras and smart locks. Offers complete protection against dust and protection against low-pressure water jets.
IP67: Perfect for smartwatches and fitness trackers. Provides complete protection against dust and can be submerged in water up to 1 meter for 30 minutes.
IP68: Great for rugged smartphones and outdoor sensors. Offers complete protection against dust and continuous immersion in water beyond 1 meter.
IP69K: Best for industrial smart devices. Provides protection against high-pressure, high-temperature water jets.

Choosing the Right IP Rating

When selecting outdoor smart technology, consider the environment and conditions in which the device will be used. For example, if you need a outdoor smart button for a partially covered patio, an IP55 rating may suffice. However, for a garden soil moisture sensor devices exposed to heavy rain, opt for higher ratings like IP67 or IP68.

By understanding IP ratings, you can make informed decisions and ensure your outdoor smart technology remains functional and reliable, no matter the weather conditions.
