## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0596:1` (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/SEN0596:1.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 carbon monoxide gas sensor differs from most [gas sensors](https://www.dfrobot.com/category-85.html) on the market as it does not provide specific gas concentration data.Instead, it detects whether the surrounding environment exceeds or falls below a fixed threshold.It operates on a wide voltage range of 5-24V, with high and low-level outputs.

The sensor is equipped with an indicator light for easy observation of its status, making it user-friendly.When the sensor detects a gas concentration above the threshold, it outputs a high-level signal and the indicator light illuminates.Conversely, when the concentration falls below the threshold, it outputs a low-level signal and the indicator light turns off.

Note: The threshold of this sensor is factory-fixed and cannot be modified by the user. Custom threshold parameters can be set for bulk orders.

If you need to measure Carbon Monoxide concentration accurately,we recommend the [Fermion: MEMS Carbon Monoxide CO Gas Detection Sensor.](https://www.dfrobot.com/product-2697.html)
