GSR SENSOR MODULE
- Interface: Analog
- Operating Power: 3.3V/5V
- Sensor: finger straps for electrodes
- Dimensions: 20 x 20mm
- Various Main Boards Support: Arduino/Seeeduino/Raspberry Pi/BeagleBone/LinkIt ONE
- This module stands for galvanic skin response and it is a method of measuring the electrical conductance of the skin.
- It can be used to reflect the human emotional activity. When people 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.
- It allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied.

ACS712 CURRENT SENSOR
- Measures both AC and DC current
- The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current or down -66mV per amp for negative current.
- Measures both AC and DC current
- Provides isolation from the load
- Easy to integrate with MCU, since it outputs analog voltage
