Test: Accelerometer- 2 - Electronics and Communication Engineering (ECE) 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. }
