&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
The Heart Rate Variability is a measure for stress. We study the effect of noise to teachers&amp;#039; stress levels using RPi.&lt;br /&gt;
&lt;br /&gt;
== Theory ==&lt;br /&gt;
&lt;br /&gt;
HRV is elsewhere. This contains the methods to connect and store the HR data from Polar Heartbeat monitor using Raspberry Pi 4.&lt;br /&gt;
