Title: Mobile EKG Sensor Senior Design May0530
1Mobile EKG SensorSenior Design May0530
ABSTRACT
The goal of this project is to develop a method
of collecting heart rates using Verniers EKG
sensor with the NI Mobile DAQ. The Mobile DAQ
must then communicate with a PDA using the
Bluetooth protocol. The data from the sensor
will be displayed in a LabVIEW module.
PROJECT REQUIREMENTS
INTRODUCTION
- Problem StatementHeart rates have always been
measured with ECG/EKG equipment that are
stationary in medical institutions. It would be
of great service to the public if there is a
device that would provide similar performance but
is portable. Since most medical problems occur
away from health institutions, such a device
would be beneficial for many situations. - Intended Users and UsesThis module has several
different applications and could be used by many
people. Some possible users are paramedics,
lifeguards, or even teachers. It will be used to
collect heart rates and produce real time graphs
of such data. It will also have its own
algorithms to process EKG data. - Assumptions
- The PDA interface will be clear and easy to use.
- All necessary EKG data will be displayed in the
PDA interface. - The manual will explain the proper use of the
sensor and the PDA interface. - The Mobile DAQ is powered by two AA batteries.
- Limitations
- The Mobile DAQ must stay within Bluetooth range
of the PDA. - Device is not reliable for use in serious medical
operations. - User must be able to run LabVIEW module on their
PDA. - Devices cannot operate outside of the temperature
range 0 to 50 C. - Expected End Product
- The final product will include the LabVIEW module
to display the EKG data as well as the EKG
sensor, Mobile DAQ, and all connectivity
accessories. Also included will be an in-depth
manual on how to use the sensor and the LabVIEW
module.
- Design Objective
- Ensure the EKG sensor can take complete and
accurate data - Ensure the MobileDAQ can read in the EKG sensors
data - Ensure the MobileDAQ can communicate with the PDA
- Ensure the MobileDAQ can communicate with the
PalmOS - Ensure the PDA and PalmOS can receive the data
- Ensure the modules created will put the EKG data
into graphical form - Ensure the manual is complete and easy to read
- Functional Requirements
- Display Data
- The data taken by the EKG sensor should have the
capabilities of being displayed graphically on
either a Bluetooth PalmOS PDA or a PocketPC 2003
PDA. - Portable
- The collective end product including the EKG
sensor, MobileDAQ, PDA, and laptop should all be
portable and functional in any location. - Accurate
- The end product should be able to take data which
is accurate when measuring someones heart rate. - Communicate Wirelessly
- The MobileDAQ should be able to communicate
wirelessly (through Bluetooth) with the Bluetooth
enable PalmOS PDA or PocketPC 2003 PDA. - Constraints Considerations
APPROACH AND CONSIDERATIONS
Technology considerations LabVIEW LabVIEW is to
be used for the algorithms used in processing the
data. There are several different versions of
LabVIEW, which may have a small effect on the
programming section. PDA vs. Laptop The
MobileDAQ can connect wirelessly to either a
Bluetooth enabled PDA or a Bluetooth enable
laptop. We will look at which is readily
available for us to use and test with, which is
cheaper, and if either has any certain limiting
capabilities. Testing requirements
considerations Location The location of where
we are placing the EKG sensors on the body while
doing our testing could affect how the EKG
sensor reads the data. As long as the location
is kept constant through the testing process,
this should not be a problem. Consistency The
data from the EKG sensor needs to work with both
the Bluetooth enabled Desktop/Laptop and the
PalmOS or PocketPC 2003 PDA. Length of test We
must decide how long we wish to record the data
using the EKG sensor. We must also decide what
length of time is appropriate.

SUMMARY
This project will prove to be an interesting and
challenging task. Successful completion of the
project will allow many institutions with low
budget to take EKG measurements. Along with a
successful end product, members of the team will
learn invaluable information regarding LabVIEW
development, the Bluetooth protocol, graphing
techniques and efficient data processing
algorithms.
