## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR1132:1` (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/DFR1132:1.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

Gravity: Linear/Analog Hall Sensor is a high-precision device designed for measuring and monitoring magnetic field strength. Advanced Hall effect circuitry at the core converts magnetic induction strength directly into a voltage output. The sensor responds uniquely to magnetic fields: when the south pole of a magnet faces the sensing surface, the magnetic field strengthens, and the output voltage rises above the midpoint, gradually increasing. When the north pole faces the sensing surface, the output voltage falls below the midpoint, gradually decreasing. High sensitivity makes this sensor ideal for applications that need precise magnetic field detection, such as industrial control, scientific research, security systems, and various electronic devices.

In summary, Gravity: Linear/Analog Hall Sensor is an efficient and accurate tool for detecting magnetic fields. It offers reliable performance and precise measurements, making it an invaluable addition to projects.
