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/CE05970:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description This light and proximity sensor detects light over a wide dynamic range (0.01 lux to 64,000 lux) and proximity within a short range of ~5cm. The LTR-559 is the same sort of sensor that you'd find next to the camera in your phone to detect when it's next to your ear and when your phone should disable the touchscreen. It's ideal for an automatic and manual nightlight switch that detects when ambient light drops below a certain level and automatically triggers something like Unicorn pHAT to come on, or just wave your hand over it to toggle the light on or off manually using proximity sensing. The LTR-559 Light and Proximity Sensor Breakout has an I2C interface and is 3.3V or 5V compatible. Like Pimoroni's other [Pimoroni breakouts](https://core-electronics.com.au/search/?q=pimoroni+breakout), Pimoroni has designed it so that you can solder a piece of right-angle header onto it and then pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 6, 9). It's also compatible with Pimoroni's fancy new [Breakout Garden](https://core-electronics.com.au/breakout-garden-hat.html), where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code. ### Features - Lite-On LTR-559ALS-01 sensor - I2C interface (address: 0x23) - IR/UV-filtering - 50.60Hz flicker rejection - 0.01 lux to 64,000 lux light detection range - ~5cm proximity detection range - 3.3V or 5V compatible - Reverse polarity protection - Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9) - Compatible with Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W - - Dimensions: 19x19x3mm - [Python library](https://github.com/pimoroni/ltr559-python) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/ltr-559als-01_ds_v1_7383036573f.pdf) ### Kit includes - LTR-559 Light and Proximity Sensor Breakout - 1x5 male header - 1x5 female right angle header ### Software Pimoroni put together a Python library that you can use to read data from your LTR-559 Light and Proximity Sensor Breakout, and an easy one-line installer to install everything. *Pimoroni's software does not support Raspbian Wheezy.* ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/l/t/ltr-559_2_of_4_1024x1024.jpg)
