This sensor incorporates two QRE1113 infra-red reflectance sensors on a single PCB, spaced just the right distance apart to build a line following robot. The PCB...

## Pricing

- **Price:** $4.68 (inc GST) — $4.25 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 1 today; more stock is typically available with a 4–7 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE04576:1` (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/CE04576:1.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

This sensor incorporates two QRE1113 infra-red reflectance sensors on a single PCB, spaced just the right distance apart to build a line following robot.

 The PCB is symmetrical with snap-off holes across the middle, so you can either use it as a pair or snap it in half to have two separate reflectance sensors.

## Features

- Analog output shows light or dark surface detected
- Perfect for line following robots
- Easy interface with Arduino
- Dimensions: 37mm x 9mm x 3mm
