The MS5611 is a new generation of high resolution altimeter sensors with SPI and I2C bus interface
Consists of a piezo-resistive sensor and a sensor interface IC. The main function is to convert the uncompensated analogue output voltage from the piezo-resistive pressure sensor to a 24-bit digital value, as well as providing a 24-bit digital value for the temperature of the sensor
Built in two types of serial interfaces: SPI and I2C. Pulling the Protocol Select pin PS to low selects the SPI protocol, pulling PS to high activates the I2C bus protocol
IIC: The external microcontroller clocks in the data through the input SCLK (Serial CLocK) and SDA (Serial Data)
SPI: The external microcontroller clocks in the data through the input SCLK (Serial CLocK) and SDI (Serial Data In)
