## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0289:1` (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/SEN0289:1.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

Do you want to switch lights by just shaking your hand? However, you may don't want to use a complicated and costly triple axis accelerometer. This digital shake sensor is sure to meet your needs. The digital shake sensor is to detect hand shaking which is only sensitive to unidirectional hand movements. The spring-type vibration switch is used to output a low-level pulse when the user shakes once in the specified direction and the on-board indicator flashes at the same time. Thanks to the unidirectional sensitivity of the vibration switch and the corresponding filter circuit, it has strong anti-shock interference capability to prevent false triggering. Simple and easy, switch controls are all in just a single shake.
