## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0364:1` (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/SEN0364:1.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

We live in a colorful world, but how much do you really know about color? Your eyes may deceive you, while the sensors don’t lie. This AS7341sensor can tell you the truth about color.

Gravity: AS7341 Visible Light Sensor employs the new generation of AS7341 spectral sensor IC launched by the well-known ARM company. The sensor features eight channels for the visible light, one channel for near-IR, and one channel without a filter. Also, it integrates a dedicated channel to detect ambient light flicker. Besides that, this sensor comes with 6 independent 16-bit ADC channels for data processing in parallel. The two on-board extra-bright LEDs can supply light in a dark environment.
