## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DEV-13956:1` (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/DEV-13956:1.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

The SparkFun Weather Shield is an easy-to-use Arduino shield that grants you access to barometric pressure, relative humidity, luminosity and temperature. There are also connections on this shield to optional sensors such as wind speed, direction, rain gauge and GPS for location and super accurate timing.

The Weather Shield utilizes the Si7021 humidity/temperature sensor, the MPL3115A2 barometric pressure sensor and the ALS-PT19 light sensor. The shield relies on the Si7021 and MPL3115A2 Arduino libraries.

Each shield comes with two unpopulated RJ11 connector spaces (for optional hookup of rain and wind sensors) and a 6-pin GPS connector (for optional hookup of a GP635T GPS module). Finally, each Weather Shield can operate from 3.3V up to 16V and has built-in voltage regulators and signal translators.

**Note:** The Weather Shield comes as a stand-alone board. Headers, connectors and additional sensors will need to be purchased separately; check the Wish List below or the Recommended Products on this page.

**Note:** This shield was designed for the SparkFun RedBoard and Arduino Uno and will not work with other boards (like the Arduino Yun, for example) without modification.

**Features:**

- Humidity/Temperature Sensor — Si7021
- Barometric Pressure — MPL3115A2
- Light Sensor — ALS-PT19
