SeeedStudio: Groove Galvanic Skin Response GSR Sensor Module (3.3V/5V) -101020052

Grove - GSR Sensor stands for galvanic skin response and it is a method of measuring the electrical conductance of the skin. It can be used to reflect human emotional activity.

Features

• Adjustable sensitivity: Adjust the sensitivity via a potentiometer
• Easy to read: Analog voltage output
• Programmable configuration: Versatile for various applications
• Low power consumption: 3.3/5V Supply, suitable for many microcontrollers and SBCs

Description

When we are emotionally stressed or have strong expressions on the face, sympathetic activity increases and promotes the secretion of sweat glands, which increases the skin's electrical conductivity.

Grove - GSR sensor or eda sensor allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. It is an interesting gear to create emotion-related projects like sleep quality monitors. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied.

We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you with guidance PDF documents.

Application

In the experiment, we inserted our fingers into the two electrode fingertips of the sensor and connected a Buzzer to the digital output of the seeeduino.

During the test, the value detected by the sensor will continue to change within a certain range. When the tester takes a deep breath, the range of the fluctuation will suddenly increase and exceed the threshold we set, and then the buzzer will be triggered.
