Making a Unique Type Of Wind Gauge For Home Assistant Use

Originally published on hackaday.com by Lewin Day on 11 November 2024

Sebastian Sokołowski has crafted a unique wind gauge, or anemometer, designed to measure wind speed and direction without relying on moving parts. Unlike traditional cup-style anemometers with vanes, his build uses a stationary approach to avoid wear and tear over time, making it a low-maintenance addition to his smart home system.

The system operates using strain gauges mounted on a 3D-printed, sail-like structure. As the wind blows against the sail, it flexes, and the strain gauges measure the amount and direction of this deflection. This innovative design enables the device to determine wind speed and direction without the need for mechanical components. Sebastian has also accounted for environmental factors, such as temperature-induced expansion and contraction, ensuring reliable performance.

This creative approach offers an intriguing alternative to traditional mechanical and ultrasonic wind sensors. It will be interesting to see how it performs in terms of accuracy, precision, and durability, particularly when compared to established designs. For those interested in innovative weather-sensing technology, Sebastian’s project is an exciting glimpse into the future of smart home integration.
