Galvanic Skin Response (GSR) Measurement Sensor - Lie Detector

GSR, standing for Galvanic Skin Response, is a method of measuring the electrical conductance of the skin. Strong emotions can stimulate your sympathetic nervous system, resulting in more sweat being secreted by the sweat glands. The Grove - GSR 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 a sleep quality monitor. Lie detectors generally work on this principle.

The product is compatible with Seeed Studio's Grove kits. In addition to these kits, it can also be easily used with many microcontroller platforms, especially Arduino® boards.
