Connecting the Vibration Sensor
Mission 1 Tutorial
Activity – General with Sensors (20 mins)
Start with all the parts of the Mission 1 on a table:
Jumping wires x 4
NOTE: The vibration sensor is polarized which means it works in one orientation only. The image below shows the correct orientation to work correctly. When viewing the face with writing “MEAS”, the left pin of the sensor should be connected through to the Ground terminal on the PCB.
1 MΩ Resistor x 1
Ask the class to name and describe each component as you connect it to the Mission 1 in front of them.
Explain briefly about each of these sensors and what they measure.
Demonstrate a simple use of the sensors already prearranged with a breadboard and jumper wires.
Follow through with the rest of the lesson using one of the available sensors. The students should be able to connect all the components on a breadboard and connect up to their Mission 1.
Once the hardware is assembled, up the Mission 1 view the data from the relevant sensor field.
Review the output of the sensor on the LCD and discuss the information.
Activity – Investigation (15 mins)
How much vibration do you experience in your spaceship (car) when you come to school each day?
What components contribute to the vibrations you experience (tyres, suspension, road, etc)?
How can you get good vibration readings?
Is the sensor stable in the breadboard?
Is clamping required?
What readings do you get when you deflect the sensor rather than knock / cause it to vibrate?
