Product Description:
The MS5540-CM is a compact and robust high-precision air pressure and height sensor designed for applications requiring accurate barometric measurements in rugged or waterproof environments. This 16-bit digital altimeter module combines a precision piezoresistive pressure sensor and an analog-to-digital converter (ADC) in a single SMD hybrid package, ensuring reliable performance with minimal power consumption.
Engineered for outdoor and embedded use, the MS5540-CM features a waterproof design that can withstand immersion up to 100 meters, conforming to ISO2281 standards. With an SPI interface and a built-in 32.768 kHz system clock, it is ideal for portable devices, GPS receivers, wearable instruments, and environmental monitoring systems.
