Sensor compatibility

[ukmaster]

Hello.

I am thinking to use a surface temperature sensor and a heart rate sensor.

Because I have no electric engineering background, I have no idea those sensors can be connected to Labview 8.0 which I am using.

Currently, I am using NI-DAQ board which has 8 channels, and Labview 8.0 software.

Could anybody help me figure out if the sensors can be applicable to my current system to get some data?

The sensor' specs are as follows.

Temperature sensor: http://www2.vernier.com/booklets/sts-bta.pdf

Heart rate sensor: http://www2.vernier.com/booklets/ehr-bta.pdf

I appreciate your help in advance.

Hi Ukmaster

After reading the specification of those two sensors and taking a look at the “Vernier” labview support; click here LabVIEW Software, you should be able to read the data from both of those sensors in LabView.

To provide you with a better support we need to know if you have “Vernier” NI-DAQ board or “National Instruments” board, because even if the “Vernier” board is a National Instruments board it looks like it was customize by “Vernier” to work with their sensors and the connection will be different.

The “Heart Rate Sensor” spec has too few information on how does it works but it does have support for LabView; to read the data from this sensor you will need the Vernier Sensor DAQ board from in the case you have a National Instruments DAQ board you should be able to read the data if it has a counter. You can read the pulses from the “wireless receiver” into a counter, for more information go to: Building a Counter Input VI in NI-DAQmx.

For the “Temperature Sensor” If you have a “Vernier” sensor DAQ board I have attached the guide they use to connect the sensor to the card. If you have one of our boards you will be able to read the data from the sensor because the temperature sensor is no more than a “thermistor”; a thermistor is a resistor that changes its resistance as a function of the temperature so when a current flow through the thermistor the voltage will change depending on the temperature an you will read this change in Labview. For more information on how a thermistor works go to: Measuring Temperature with an RTD or Thermistor.  

I hope it helps
