The MS5541-CM is a high-resolution altitude sensor manufactured by Intersema Sensoric SA (now Measurement Specialties, a TE Connectivity company). It is a miniature, surface mount device featuring a piezoresistive pressure sensor and an ADC interface. It is primarily designed for mobile altimeter and barometer systems.

Applications:

• Mobile Altimeters
• Barometric Systems
• Weather Stations
• GPS Applications
• Wearable Devices

Features:

• High-Resolution Pressure Sensor
• Integrated ADC
• Digital Output
• Low Power Consumption
• Small Size

Benefits:

• Accurate Altitude Measurement: Provides precise altitude readings due to its high-resolution pressure sensor.
• Digital Interface: Simplifies integration with microcontrollers and other digital systems.
• Low Power: Consumes minimal power, making it suitable for battery-powered devices.
• Compact Size: Enables integration into small, portable devices.

Additional Details:

The MS5541-CM uses a piezoresistive pressure sensor, which changes its resistance in response to pressure variations. The integrated ADC converts the analog pressure signal into a digital value. The sensor typically communicates with a microcontroller via a serial interface, such as SPI or I2C. It is calibrated to provide accurate altitude and pressure readings over a wide temperature range. Because of its small size and low power consumption, it is especially well suited for use in portable devices, such as smartphones, smartwatches, and handheld GPS units. The device is supplied in a ceramic package suitable for SMT assembly.
