## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0592:1` (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/SEN0592:1.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

The ultrasonic [distance range sensor](https://www.dfrobot.com/category-55.html) uses ultrasonic technology to detect obstacles up to 5 meters away in robot automation control applications.

It offers advantages such as small blind zones (Measurement accuracy: 1 + (S \* 0.3%) cm),narrow measurement angles (horizontal 40-65°, vertical 60-80°),short response times only 15-750ms,filtering of same-frequency interference,compact size, high installation adaptability,IP67 dust and waterproof capabilities,long lifespan and high reliability.

Utilizing innovative ultrasound processing technology, it can identify and filter out foreign ultrasound, resulting in more stable and reliable data output. This greatly reduces the probability of same-frequency interference, meeting the complex environmental application requirements in the field of robot automation control.

It features RS4585 output for sensor data, and users can use it in conjunction with [Arduino TTL to RS485 expansion board](https://www.dfrobot.com/product-1024.html). It finds wide applications in robot obstacle avoidance, automatic control, parking management systems, security gate detection, access control systems, and object proximity and presence detection.
