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/SEN0617:1.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 The DFRobot Gravity BME688 Environmental Sensor is an advanced, compact MEMS sensor that provides accurate measurements of **temperature, humidity, barometric pressure**, and volatile organic compounds (**VOC**).It supports **I2C/SPI** communication protocols, which facilitate integration with various systems.It also serves as a data source for **AI gas analysis**, making it an ideal choice for applications requiring precise environmental monitoring and intelligent gas detection. This sensor is well-suited for DIY weather stations, portable environmental monitoring devices, smart home systems, and agricultural monitoring. **AI Gas Analysis** The BME688’s AI-driven gas analysis capability sets it apart from the previous BME680 model. It is particularly valuable for air quality monitoring systems, environmental research, and industrial safety. Using the Bosch [BME AI-Studio](https://www.bosch-presse.de/pressportal/de/en/bme-ai-studio-software-225349.html) and [BSEC2-Arduino](https://github.com/BoschSensortec/Bosch-BSEC2-Library) library, customized AI gas analysis can be implemented to detect and analyze specific gas profiles. ![BME688 AI Gas Analysis](https://core-electronics.com.au/attachments/uploads/SEN0617-2.jpg) **Highly Accurate Environmental Sensing** The BME688 sensor enhances the precision of temperature measurements, boasting an accuracy of ±0.5°C. These improvements render the sensor ideal for applications requiring highly accurate environmental data, including scientific experiments, climate research, and industrial environmental monitoring. **Advanced Air Quality Monitoring** The Gravity BME688 excels in indoor air quality monitoring, detecting harmful VOCs and providing real-time data for smart homes. Its built-in heating layer ensures stable, accurate measurements by minimizing ambient interference. ![IAQ(Indoor Air Quality) Comparison Table](https://core-electronics.com.au/attachments/uploads/SEN0617-3.jpg) **Compact Design** With dimensions of just 22\*30mm, the BME688 is ideal for compact and portable weather stations, smart home setups, and agricultural monitoring systems. ![Compact Design](https://core-electronics.com.au/attachments/uploads/SEN0617-4.jpg) ### Applications DIY weather stations Portable environmental monitoring devices Smart home systems Agricultural monitoring ### Specification **Power Requirements** Operating Voltage: 3.3 to 5V DCOperating Current: 5mA (25mA with VOC Measurement Enabled) **Output Signal** Interface Options: I2C/SPI **Temperature Sensor** Measurement Range: -40 to +85°CAccuracy: ±0.5°C (0 to 65°C) **Humidity Sensor** Measurement Range: 0 to 100% Relative Humidity (R.H.)
