MS5837-30BA High - resolution Pressure Sensor For Depth Measurement Systems
Product Introduction:
MS5837 - 30BA is a high - resolution pressure sensor with an I2C interface. It includes a high - linearity pressure sensor and an ultra - low - power 24 - bit sigma - delta analog - to - digital converter (ADC) with internally factory - calibrated coefficients. It can provide a precise 24 - bit digital pressure and temperature value, and has various operation modes, allowing users to optimize conversion speed and current consumption.
Working Principle:
It consists of a piezoresistive sensor and a sensor interface IC. The main function is to convert the uncompensated analog output voltage of the piezoresistive pressure sensor into a 24 - bit digital value, and at the same time, provide a 24 - bit digital value for the sensor temperature. The external microcontroller reads the data through the serial clock (SCL) and serial data (SDA) pins. The SDA pin is bidirectional, and this interface only uses two signal lines without the need for a chip - select pin.
Application Scenarios:
It is mainly used in depth measurement systems, and can also be used in applications such as altimeters, weather stations, and industrial pressure monitoring due to its high - precision pressure and temperature measurement functions. It is suitable for equipment that requires high - precision depth measurement, such as underwater robots, diving computers, etc..
