PERIPHERAL MODULE  
Digital Pressure Sensor  
General Description  
The MS5637 peripheral module provides the necessary hardware to interface  
the MS5637 digital barometric pressure and temperature sensor to any system  
that utilizes Pmod compatible expansion ports configurable for I2C  
communication. The MS5637 sensor is a self-contained pressure and  
temperature sensor that is fully calibrated during manufacture. The sensor can  
operate from 1.5V to 3.6V. The sensor module includes a high-linearity pressure  
sensor and an ultra-low power 24 bit _Σ ADC with internal factory-calibrated  
coefficients.

Digital Pressure Sensor  
Detailed Description  
I2C Interface  
The peripheral module can interface to the host in one of two ways. It can plug directly into a Pmod-compatible port (configured for I2C)  
through connector J1, or in this case, other I2C boards can attach to the same I2C bus through connector J2.  
I2C Interface (Daisy Chaining Modules)  
2
Alternatively, the peripheral module can connect to other I C-based Pmod modules through the expansion J2 connector. Connector J1  
provides connection of the module to the Pmod host. The pin assignments and functions adhere to the Pmod standard as shown in Table 1.  
2
2
The J2 connector allows the module to be connected through a daisy-chain from another I C module and/or provide I C and power  
2
connections to other I C modules on the same bus. See Table 2.  
External Control Signals  
The IC operates as an I2C slave using the standard 2 wire I2C connection scheme. The IC is controlled either by the host (through the Pmod  
connector). In cases where one or more of the SCL and SDA signals are driven from an external source, resistors R1, R2 provide pull-up.  
However, this also increases the apparent load to the external driving source. If the external source is incapable of driving these loads, they  
should be removed.
