## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-23715:1` (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/SEN-23715:1.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 SEN55 environmental node is a straightforward, all-in-one sensor solution platform for the accurate measurement of various environmental parameters, such as particulate matter, volatile organic compounds (VOCs), oxidizing gases, such as nitrogen oxides (NOx), as well as humidity & temperature.

Thanks to proprietary algorithms, the module enables straightforward integration into various applications. This allows you to save valuable project time and personnel resources compared to integrating all of these separately. The SEN55 provides reliable air quality measurement data.

**Note:** Sparkfun provide an interface cable as well. A feature not found elsewhere.
