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/SS101020634:1.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 **![](https://core-electronics.com.au/attachments/localcontent/1_27386f0b797.png)** ![](https://core-electronics.com.au/attachments/localcontent/3_600259a26ca.png) ![](https://core-electronics.com.au/attachments/localcontent/4_86547316832.png)![](https://core-electronics.com.au/attachments/localcontent/55_995723d508b.png)![](https://core-electronics.com.au/attachments/localcontent/6_1776739fe3c.png)![](https://core-electronics.com.au/attachments/localcontent/7_34973a73979.png) **Key Features** - NDIR CO2 sensor technology: embedded with Sensirion SCD30 - Multi-function: Integrates temperature and humidity sensor on the same sensor module - High precision and wide measurement accuracy: ±(30 ppm + 3%) between 400ppm to 10'000ppm - Superior stability: Dual-channel detection - Easy project operation: Digital interface I2C, Breadboard-friendly, Grove compatible - Best performance-to-price ratio **Description** The Grove - SCD30 is a 3-in-1 Arduino sensor that can measure CO2, temperature, and humidity. Based on Sensirion SCD30, it is a Non-Dispersive Infrared(NDIR) carbon dioxide sensor with high precision and wide measurement accuracy which can reach ±(30 ppm + 3%) between 400ppm to 10'000ppm. It would be a perfect choice if you are not looking for a simple Arduino temperature sensor or a CO2 sensor, but a multifunctional sensor for your Arduino weather station or other environmental projects.We've released the [Seeed Gas Sensor Selection Guide](https://wiki.seeedstudio.com/Sensor_gas/) and the [Grove Selection Guide](https://docs.google.com/spreadsheets/d/123yBkwL2mo8Zt2CCPW4_MX4TCSTSj8BVLRSmSZeEYzg/edit#gid=1056399402), it will help you choose the Grove that best suits your needs.Embedded with Sensirion SCD30, The Grove - SCD30 integrates [Non-Dispersive Infrared(NDIR)](https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor) measurement technology for CO2 detection. It also has Sensirion humidity and temperature sensors on the same sensor module. You can see that there is a monkey face graphic on the module, actually, this is a carbon dioxide molecular model. As you can see, the 4 valence electrons on each oxygen atom and also the covalent bonds between the carbon and oxygen atoms are clearly shown. ![](https://core-electronics.com.au/attachments/localcontent/MONKEY_715745379b3.png) Here is a lewis structure of the CO2 molecule: ![](https://core-electronics.com.au/attachments/localcontent/CO2_3027787aff3.png) **Application Ideas** - Air Purifier - Environmental Monitoring - Plant Environmental Monitoring system - Arduino weather station **Pinout** **![](https://core-electronics.com.au/attachments/localcontent/PIN_20326ea3aaf.jpg)** **ECCN/HTS** | HSCODE | 9027100090 | |---|---| | USHSCODE | 9026208000 | | UPC | ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_823.jpg)
