Test: Accelerometer- 2 - GATE MCQ

What was the original name of the first accelerometer?

AC (Alternating Current) response accelerometer cannot measure constant or static acceleration.

What is the use of the ADXL-335 sensor?

How many pins are present in the ADXL-335?

What mode should the 3 axis pins of the ADXL-335 be read in, in an Arduino in order to obtain meaningful values?

What will happen if we supply a voltage of 25V to the Vcc of the ADXL-335 sensor?

Which of the formulae give us the value of acceleration for the x-axis in the ADXL-335?

Which of the formulae give us the angle of inclination in the ADXL-335?

Can you measure the acceleration of a train, if the train is moving at a constant velocity and the sensor is located on the train?

What kind of sensor is the ADXL-335 Accelerometer Module?

The ADXL-335 Accelerometer sensor module uses capacitive technology to detect changes. The Equation governing that function is given by C=f(A/d). What is the meaning of ‘A’ in the equation?

What is the drawback of the code given below?

1. int val, Vref=5;

2. void setup() {

3. Serial.begin(9600);

4. }

5. void loop() {

6. val= (((analogRead(A3) * Vref) / 1024) – 1.65) / 0.330;

7. }
