## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0312:1` (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/SEN0312:1.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

An ultrasonic distance[ sensor](https://www.dfrobot.com/category-36.html) determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This Waterproof Ultrasonic Sensor features a farther monitoring distance, wider detection range, and good penetration power(smog, dust).

**Connection with[ Arduino](https://www.dfrobot.com/category-35.html)**

The ultrasonic sensor adopts a closed probe consisting of a transmitter & receiver, waterproof and dustproof. All the signal processing units are integrated inside the [module](https://www.dfrobot.com/category-156.html), so users can directly obtain the distance value through a Serial Interface. With a 9600bit/s baud rate, the [sensor](https://www.dfrobot.com/category-36.html) can easily communicate with upper-host or other MCU, which greatly shortens the developing cycle for users.

**Connection with [Raspberry Pi](https://www.dfrobot.com/category-36.html)**

Use the sensor with [Arduino](https://www.dfrobot.com/category-35.html) controller to build up your projects, such as a car reverse distance sensor, obstacle avoiding robot, approaching object detection etc.
