## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0376:1` (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/SEN0376:1.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 is an [Arduino](https://www.dfrobot.com/topic-277.html) compatible alcohol sensor module from DFRobot with a 0-5ppm measuring range, supporting I2C and UART outputs. Aiming at fast and accurate detection of alcohol gas concentration in the air, the sensor is well applicable to the small alcohol concentration measurement in the breathalyzer, smart vehicle, and so on.

Based on the electrochemistry principle, this alcohol sensor has been calibrated before the factory. It is characterized by strong anti-interference, high stability, and sensitivity and up to 2 years of service life. The module supports 0.01ppm(10ppb) resolution and 3.3~5.5V wide-range voltage input and works well with mainstream controllers like [Arduino](https://www.dfrobot.com/topic-277.html), [ESP32](https://www.dfrobot.com/product-1798.html), and [Raspberry Pi](https://www.dfrobot.com/product-2133.html). With the easy-to-use Gravity interface and the sample program provided by us, you can conveniently build your alcohol concentration detector using this sensor.
