## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0429:1` (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/SEN0429:1.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 TMF8701 is a time-of-flight (ToF) distance ranging sensor that uses the time difference between light pulses to measure distance. It provides single zone detection of an object irrespective of the color, reflectivity and texture of the object.

The TMF8701 offers high dynamic range and operates in either a proximity mode (1 –10cm) or a ranging mode (10–60cm) for detection sensing. And the device can make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight.

A built-in histogram is featured to delivers dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters.

The TMF8701 outputs data through a I2C fast-mode communications interface and an integrated micro controller, which is featured with all algorithms included on-chip with no need for external optics.
