Digital Air Pressure Sensor MS5540-CM Waterproof High-Precision Height Module With Water Depth Of 100mItem NO.: MS5540-CM

MS5540C (RoHS) Micro Barometer Module

Product Description:

The MS5540C is a SMD hybrid device that includes high-precision piezoresistive pressure sensors and ADC interface ICs. It is a micro version of the MS5534C barometer/altimeter module and provides 16 bit pressure and temperature parameters depending on voltage. The MS5540C is a low-voltage, low-power device with an automatic power off switch. The 3-wire interface can meet various communication requirements with microprocessors. Improved pressure range compared to MS5534A (measured down to 10 mbar). Compared to the MS5534B and MS5540B, the previous 15-bit output has been upgraded 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, and MS5540B. In addition, the MS5540C is compatible with its external dimensions to the pressure sensor MS54xx series. The adhesive protection of the sensor can meet the use of waterproof watches in a water depth of 100 meters without any other protection.
