Modbus & Arduino ready. Start robust monitoring!... ## Pricing - **Price:** $429.95 (inc GST) — $390.86 AUD, exc GST ## Availability & dispatch - Available with a lead time — expect dispatch between Sep 21 and Sep 23. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0657:1` (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/SEN0657:1.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 Tired of juggling multiple sensors for comprehensive weather data? This ultrasonic all-in-one RS485 7-in-1 Weather Station delivers precise environmental insights, simplifying setup and integration, especially with [Arduino](https://core-electronics.com.au/arduino.html) systems. Get reliable measurements for **wind speed and direction, temperature, humidity, atmospheric pressure, light intensity, and rainfall** from a single, robust unit. **All-in-One Precision Sensing with Advanced Technology** Gain a complete environmental picture with seven crucial meteorological parameters measured by this single, integrated sensor. It features advanced ultrasonic wind sensing – meaning no moving parts for superior accuracy, longevity, and minimal maintenance – alongside a highly sensitive optical tipping bucket rain gauge (resolution 0.1mm, accuracy ±4%). This ensures you receive comprehensive and reliable data for all key weather conditions. ![High Accuracy Optical Tipping Bucket Rain Gauge](https://dfimg.dfrobot.com/enshop/image/data/SEN0657/1.png) Figure: High Accuracy Optical Tipping Bucket Rain Gauge **Robust Industrial-Grade Design & Communication** Engineered for dependability in harsh outdoor environments, the UV-resistant, IP54 waterproof ABS housing ensures long-term performance.
