## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0287:1` (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/SEN0287:1.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**  When you want to measure the AC current, are you still having trouble cutting the wires, wiring or soldering. [Gravity](https://www.dfrobot.com/search-Gravity.html): Analog [AC Current Sensor](https://www.dfrobot.com/search-AC%20Current%20Sensor.html) comes to the rescue, eliminating the need to cut wires or reconnect circuits. Simply clamp the AC transformer probe on the AC line, and then plug the 3.5mm headphone jack into the signal conversion module to read the current AC current value. The analog output is designed to be compatible with 3V3/5V micro-controller. It can be conveniently used for AC current measurement to monitor [AC motors](https://www.dfrobot.com/search-AC%20motors.html), [lighting equipment](https://www.dfrobot.com/search-lighting%20equipment.html), air compressors, etc. **Connection Diagram**
