## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=KIT0176:1` (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/KIT0176:1.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

The weight sensor is a practical sensor close to daily life scenes. It can make many interesting applications by acquiring the weight information of objects, such as household electronic scales, daily necessities remaining alarms, and Internet of Things weighing platforms. The weight sensor and HX711 signal transfer module are already available in the DFRobot mall. However, due to the difficulty of constructing the structure, many friends cannot use this sensor based on the inability to build the structure.

This weight sensor kit reduces the difficulty of structure construction so that you can conveniently make an electronic scale, and get the weight information of the object easily. In addition, because everyone has different installation methods and usage habits, the sensor needs to be calibrated. The traditional method is to use a separate calibration code to obtain the calibration value, In order to optimize this problem, the signal transfer board in this kit has a built-in calibration algorithm, which can calibrate the weight information with one click, and there is no need to run a separate code for calibration.
