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/SEN0658:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Unlock comprehensive environmental insights with a single, robust device. The Ultrasonic RS485 9-in-1 Weather Station Sensor delivers precise data on nine critical meteorological parameters **(wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5, and PM10),** eliminating the need for multiple individual sensors. Ideal for [Arduino](https://core-electronics.com.au/arduino.html) projects, agricultural management, and smart city applications, it provides a complete picture of local weather conditions. **Comprehensive & Accurate Multi-Parameter Sensing** Obtain a complete and precise environmental overview with this all-in-one sensor. It simultaneously measures ultrasonic wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5, and PM10 particulate matter. The advanced ultrasonic technology for wind measurement ensures superior accuracy and durability with no moving parts, minimizing wear, eliminating on-site calibration needs, and offering reliable performance even in strong winds for lower maintenance and extended service life. ![High Accuracy Optical Tipping Bucket Rain Gauge](https://dfimg.dfrobot.com/enshop/image/data/SEN0658/1.png) Figure: High Accuracy Optical Tipping Bucket Rain Gauge **Robust Design for Reliable Outdoor Deployment** Engineered for resilience in diverse conditions, this sensor features a UV-resistant and waterproof ABS polymer plastic housing (IP54 rated).
