Gravity: BME688 Environmental Sensor

The DFRobot Gravity BME688 is a highly integrated MEMS environmental sensor measuring temperature, humidity, barometric pressure, and VOC index. Fully software/hardware compatible with BME680, it’s a drop-in replacement without adjustments. Key improvements: enhanced temperature accuracy, IC periphery optimization to reduce external heat impact, and a chip-bottom heating layer. This layer precisely controls sensor temp to minimize ambient interference on VOC readings, and allows adjusting temp to collect specific gas response data for AI analysis. For AI gas analysis, use Bosch’s BME AI-Studio and BSEC2-Arduino library.
