DFRobot SEN0664 Barometric Pressure & Temperature Sensor
DFRobot SEN0664 Gravity Barometric Pressure and Temperature Sensor brings industrial-grade reliability to challenging projects by integrating the advanced Bosch BMP585 chip into a rugged, gel-filled design. Built to withstand water, moisture, and chemical exposure, this waterproof barometric module overcomes the durability limitations of traditional sensors while delivering exceptional ±0.3hPa absolute accuracy and ultra-low noise (＜ 0.1Pa). Capable of detecting centimeter-level altitude changes with minimal power consumption (700μA), the environmental sensing unit supports both I2C and UART interfaces. These features make the DFRobot SEN0664 a superior choice for drone altitude stabilization, outdoor meteorological monitoring, and precision navigation systems that require long-term stability in demanding conditions.
