Session 3

We intend to find out the length of paper produced at a paper factory, (in meters)

Name the device that can be used in this situation.

• Rotatory Encoder

• Metric Tape

• AI Camera

• IR sensor

You intended to weigh the veggies being supplied by an untrustworthy vendor and expose him to the public. Select the tool that enables you to accomplish this.

• Strain Gauge

• ADC and Strain Gauge

• DAC and Strain Gauge

• All of the above

What device does NASA use in their satellite to cool the interior parts?

• Peltier module

• Compressor

• Radiator

• None of the above

How to calibrate in measuring weight scale?

• Using the scale without any reference to known standards.

• Placing objects of varying weights on the scale and using the average reading.

• Comparing the scale readings to a set of certified weights.

• Adjusting the scale based on personal estimation.

The robotic arm you're creating has to be able to accurately measure the weight of the objects it lifts.
Which of the following can be used to accomplish the task?

• Force-sensitive resistor (FSR)

• Load cell

• Pressure sensor

• All of the above

You are working on a project that calls for you to identify an object's color.
Which sensor would you use for sensing the color?

• CCD sensor

• Spectrometer

• Colorimeter

• RGB sensor

How would you find the heat waves sent by the Predator alien, as Arnold

what sensor would you use?

• PIR sensor

• Infra-red receiver

• Infra-red camera

• All of the above

The following query is posed to you during an interview

"What is the microcontroller used in Arduino UNO?"

How would you react?

• ATmega328p

• ATmega2560

• ATmega32114

• AT91SAM3x8E

You are designing a system to detect the presence of an object on a conveyor belt.

Which sensor would you use?

• Ultrasonic sensor

• Pressure sensor

• IR sensor

• All of the above

Temperature measurement is a goal of the Arduino weather station that is being constructed.

Which sensor is most suited for this kind of application?

• Ultrasonic sensor

• DHT11

• PIR Sensor

• None of the above
