## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0214:1` (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/SEN0214:1.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

**Introduction**

 This Gravity Analog 20A current sensor is based on the Hall current sensing principle. It can be used for AC or DC current measurement, has a wide voltage range, a small footprint, requires no soldering and has a high level of precision. We have added high-voltage isolation in the circuit design for safety reasons and a non-conductive acrylic plate has been attached to the bottom of the PCB to prevent accidents such as short circuits, electric shocks and any other potential danger. This component is the newest member of our Gravity series. All Gravity components include a standard 3-pin interface to make it simple to use and easy to connect to all Arduino compatible boards. It is ideal for any automation control applications.
