## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0483:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN0483:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This wind speed sensor is a professional meteorological instrument used to measure horizontal wind speed within 0~32.4m/s. It integrates a hall sensor inside. The shell and wind cups are made of aluminum alloy material and use special mold precision die casting process, featuring small dimension tolerance and high surface accuracy. The sensor internal circuit is protected, which makes the sensor have the properties of high strength, weather resistance, anti-corrosion, and waterproof. The cable connector adopts corrosion-resistant military plug that ensures the long service life of the product.

A low-inertia anemometer is used to sense the wind speed. When the wind blows the wind cup to rotate, it drives the axle magnet to rotate through the shaft, then the accurate wind speed information can be obtained after calculation. This high-cost performance sensor can be widely used in meteorology, ocean, environment, airports, ports, laboratories, industry, agriculture and transportation.

If you are using this wind speed sensor alongside the [RS485 Wind Direction Transmitter](https://core-electronics.com.au/rs485-wind-direction-transmitter.html) you will need to change the address on one unit. You can find [instructions on how to change the address on our forum](https://forum.core-electronics.com.au/t/rs485-sen0482-sen0483-wind-speed-direction-arduino/15397).
