MS5540CM Digital sensor MS5540CM
Absolute pressure range: 10 - 1100 mbar * Resolution 0.1 mbar and 0.01°C * Chip memory 6 parameters for software compensation * Piezoresistive silicon microsensor* Integrated miniature pressure sensor 6.2x6.4mm *16-bit ADC, SPI interface *3-wire serial interface *1 system clock (32.768 kHz) *Operating voltage: 2.2 V~3.6 V *Operating currentmicroprocessorof all kinds of communications. Compared to the MS5534A, the pressure range has been improved (measured down to 10 mbar). Compared to the MS5534B, the MS5540B has been upgraded from a previous 15-bit output to a 16-bit digital output. Other improvements include:ESD sensitivity, current consumption, and exchanger accuracy. The MS5540C software is compatible with MS5534A, MS5534B, MS5534C, MS5540B. In addition to this, the MS5540C is compatible with its outer dimensional scale压力传感器MS54xx series. The adhesive protection of the sensor can be used in waterproof watches at a depth of 100 meters without any other protection. Application: * Portable altimeter/barometer system * Weather control system * Wild adventure or multi-mode watch * Backup current
