ماژول سنسور فشار بارومتریک CJMCU-MS5540C

Introduction
The MS5540C is an SMD hybrid device that includes a high-precision piezoresistive pressure transducer and an ADC IC interface. This is a miniature version of the MS5534C barometer / altimeter module and provides 16-bit pressure and temperature voltage parameters.
MS5540C is a low voltage, low power consumption with automatic power switch. Pants for children by 3, the wire interface accommodates various communications with the microprocessor and has an improved pressure range (measured up to 10 mbar) compared to the MS5534A.
Compared to the MS5534B MS5540B, it was upgraded from the previous 15-bit output 16-bit electronic cigarettes with digital output. Other improvements include ESD sensitivity, current consumption, and heat exchanger accuracy. Software MS5540C Compatible with MS5534A, MS5534B, MS5534C and MS5540B.In addition to this, the MS5540C is compatible with external measurement to the MS54xx series of pressure sensors. Sensor glue protection is sufficient for a waterproof watch with a water depth of 100 meters without any other protection.
