## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0561:1` (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/SEN0561:1.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

This GR10-30 gesture sensor is capable of recognizing **12 hand gestures**: move up, down, left, right, forward, backward, rotate clockwise and counterclockwise, rotate clockwise and counterclockwise continuously, hover, and wave. And users can set parameters such as the gesture trigger distance, the hand rotation angle, the hovering time that can be recognized, and the size of the recognition window to get more accurate results.

The GR10-30 features stable performance and high accuracy within a sensing distance of up to **30 cm**. Meanwhile, it provides two interrupt pins for indicating if a gesture trigger occurs and if an object enters the recognition range.

The sensor is well suited to non-contact operation applications like gesture remote controllers, robot interaction, human-machine interface control, lighting control, and gesture game machine.
