## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS101020044:1` (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/SS101020044:1.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 Alcohol sensor is a type of gas sensor that is designed to detect the presence of alcohol vapor in the air. It is a type of semiconductor sensor, which means that it works by detecting changes in the electrical conductivity of a material in response to the presence of alcohol.

These types of sensors have several advantages for alcohol detection. They are highly sensitive, meaning they can detect even trace amounts of alcohol in the air. They also have a fast response time, which means they can detect alcohol quickly and accurately.
