Air pressure sensor Weather Station /barometer systems Pressure sensor

DESCRIPTIONS:

The MS5540C is a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADCInterface IC. It is a miniature version of the MS5534C barometer/altimeter module and provides a 16 Bit data word from a pressure and temperature dependent voltage. MS5540C is a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a microcontroller.

FEATURES:

• 10 - 1100 mbar absolute pressure range
• 6 coefficients for software compensation stored on-chip
• Piezoresistive silicon micromachined sensor
• Integrated miniature pressure sensor 6.2 x 6.4 mm
• 16 Bit ADC
• 3-wire serial interface
• 1 system clock line (32.768 kHz)
• Low voltage and low power consumption

APPLICATIONS:

• Mobile altimeter / barometer systems
• Weather control systems
• Adventure or multi-mode watches
• GPS receivers
