MS5540C Digital Air Pressure Sensor Module Waterproof high Precision 10-1100 mBar 16 Bit 100 Meters CJMCU-MS5540C
Note:
Do not touch the white gel part of the sensor, which may damage the sensor.
Product Features
- The MS5540C is an SMD hybrid device that includes a high precision piezoresistive pressure sensor and an ADC interface IC. It is a miniature version of the MS5534C barometer/altimeter module and provides 16-bit pressure and temperature parameters by voltage.
- The MS5540C is a low voltage, low power device with an automatic power down switch. The 3-wire interface accommodates various communications with the microprocessor and has an improved pressure range (measured down to 10 mbar) compared to the MS5534A.
- Compared to the MS5534B MS5540B, it has been upgraded from the 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, and MS5540B.
- In addition to this, the MS5540C is compatible from its external dimension to the MS54xx series of pressure sensors. The sensor's adhesive protection is sufficient for waterproof watches with a water depth of 100 meters without any other protection.
