## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0343:1` (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/SEN0343:1.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 high-resolution differential pressure sensor with I2C communication is used to measure the difference in pressure across two points on a device. A high-performance MEMS pressure chip and a special conditioning chip are encapsulated inside the sensor. It will give you a comparative measurement between two points. Besides, the sensor IC adopts a unique multi-stage temperature-compensation algorithm to reduce the effect of the environment on the sensor output.

Note: In order to ensure the measurement resolution and the sensor life, please use the sensor in the clean air. Do not let water enter the nozzle of the sensor, or it will cause damage to the sensor.
