MS8607
PERIPHERAL MODULE
Digital Pressure and Humidity Sensor
General Description
The MS8607 peripheral module provides the necessary hardware to interface
the MS8607 digital pressure, relative humidity and temperature sensor to any
system that utilizes Xplained pro compatible expansion ports configurable for
I
2
C communication. The MS8607 sensor is a self-contained pressure, humidity
and temperature sensor that is fully calibrated during manufacture. The sensor
can operate from 1.5V to 3.6V. The MS8607 is ideal for weather station
applications embedded into compact devices and any applications in which
pressure, humidity and temperature monitoring is required.

Detailed Description
I
2
C Interface
The peripheral module can interface to the host being plugged directly into an Xplained Pro extension port (configured for I2C) through
connector JP1
External Control Signals
The IC operates as an I
2
C slave using the standard 2 wire I
2
C connection scheme. The IC is controlled either by the host (through the
Xplained pro 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.
