Barometric pressure sensor MSP series

MEMSdigitalI2C

The barometer product adopts a unique LGA packaging form, which has been verified for a long time and is stable and reliable. The atmospheric pressure measuring device with high stability can provide accurate digital signal output linearly related to the external sensing pressure. Product features: The barometer product adopts a unique LGA packaging form, which has been verified for a long time and is stable and reliable. The atmospheric pressure measuring device with high stability can provide accurate digital signal output linearly related to the external sensing pressure. The waterproof barometer covers more pressure ranges and can measure atmospheric pressure. At the same time, it can also use the linear relationship between liquid level depth and pressure to measure depth. The waterproof adhesive with medium isolation can not only realize pressure transmission, but also protect devices from seawater corrosion. It is suitable for wearable products, such as bracelets and watches. The MEMS pressure sensor adopts the advanced ion implantation process and the sensa process with the unique patented technology of sensitive core Co., Ltd. the sensa process not only ensures the long-term stability and reliability of the product, but also realizes low cost. The device is internally integrated with 24 bit sigma delta ADC, OTP memory and i2c/spi communication interface. External MCU reads ADC converted data through i2c/spi communication interface, and reads device calibration parameters stored in OTP. Through specific calibration formula, the current pressure value (PA) can be calculated.
