Suggested experiments   

The following experiments can be performed with the Blood Pressure sensor:  

 

Using the oscillometric method to calculate blood pressure.  

 

Measure blood pressure before and after exercise and while sitting or standing; 

 

Compare blood pressure after voluntary isometric contractions (weight lifting) and a 
rhythmic activity such as running or biking; 

 

Study the effect of caffeine on blood pressure.
