GSR stands for?
A. galvanic skin response
B. glands skin response
C. grove skin response
D. grove stimulus response
Explanation: GSR stands for galvanic skin response, is a method of measuring the electrical conductance of the skin.
What is Operating voltage?
Explanation: Operating voltage : 3.3V/5V
In Hardware, Connect the Grove-GSR to?
Explanation: Connect the Grove-GSR to A0 on Base Shield.
Connect Seeeduino-V4.2 to PC by using a ?
A. UCB cable
B. UAB cable
C. USB cable
D. UTB cable
Explanation: Connect Seeeduino-V4.2 to PC by using a USB cable.
Which is the Input Signal?
D. None of the above
Explanation: Input Signal : Resistance, NOT Conductivity
How many pins are present in the GSR Sensor?
Explanation: The GSR Sensor has 4 pins. These are the Vcc for powering the sensor, GND for completing the circuit, and SIG and NC being the data pins.
What kind of output does the SIG pin give?
Explanation: The SIG pin gives us the actual data received by the sensor, and since the value can fluctuate very easily it is an Analog pin.
How many electrodes does the GSR Sensor need?
Explanation: The GSR Sensor needs 2 electrodes to complete the circuit with your body in order to obtain a reading. The sensor records the resistance formed by the load that is your body and outputs the data to the A0 or the SIG pin.
What kind of sensor is the GSR Sensor?
D. Pressure based
Explanation: The GSR sensor is an active sensor since it requires an active DC voltage source to function properly. On the contrary, an LDR can be said to be a sort of a passive sensor since it does not require the input of current from an external source for its working.
Grove-GSR Sensor measures the resistance of the people, NOT Conductivity?
C. Can be true or false
D. Can not say
Explanation: True, Grove-GSR Sensor measures the resistance of the people, NOT Conductivity!
