DFRobot SEN0665 Barometric Pressure & Temperature Sensor

DFRobot SEN0665 Gravity Barometric Pressure and Temperature Sensor is a professional-grade digital altimeter designed for applications requiring extreme vertical stability and environmental accuracy. Powered by the next-generation Bosch BMP581, this atmospheric pressure monitor delivers best-in-class absolute accuracy of ±0.3hPa and ultra-low noise (＜ 0.1Pa). Unlike standard modules, it supports native 3.3V/5V operation and offers flexible I²C/UART interfaces, ensuring seamless plug-and-play integration. The DFRobot SEN0665 precision sensor is the optimal solution for drone altitude hold, indoor navigation, and meteorological data logging, where data reliability is critical.
