SEN0665

SEN0665 is a Gravity: BMP581 barometric pressure sensor (±0.3hPa high accuracy, I2C / UART) board. This 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 features native 3.3V/5V compatibility and flexible I2C/UART interfaces, ensuring seamless plug-and-play integration. This precision sensor is the optimal solution for drone altitude hold, indoor navigation, and meteorological data logging where data reliability is critical.
