6.1.1 - Sensors Flashcards
1
Q
acoustic sensors and example [3]
A
- measure sound waves in surrounding environment
- detect and convert sound signals into electrical signals
- e.g. voice recognition
2
Q
accelerometer and example [3]
A
- measures acceleration in 3D space
- detects change in velocity
- e.g. smartphones
3
Q
flow sensors and example [2]
A
- measure rate at which fluids or gases flow through a system
- e.g. water management
4
Q
gas sensors and example [3]
A
- detects and measure specific gases concentration in surrounding environment
- monitors greenhouse gas levels
- e.g. vehicle exhaust
5
Q
humidity sensors and example [3]
A
- measures amount of water vapour in air
- compares vapour in air to max amount it can hold at specific temperature
- e.g. food storage
6
Q
infrared sensors and example [3]
A
- detects and measures heat signatures, motion and proximity
- senses body heat or movement
- e.g. remote controls for tv
7
Q
level sensors and example [3]
A
- measures levels of liquids or solids in containers
- needed for real-time monitoring in process control
- e.g. water management
8
Q
light sensors and example [3]
A
- measure intensity or presence of light in their surroundings
- converts light energy to electrical signals
- e.g. security systems
9
Q
pressure sensors and example [3]
A
- measures force applied by a fluid to a specific area
- converts pressure to electrical signals
- e.g. blood pressure monitors
10
Q
proximity sensors and example [3]
A
- measures distance or presence of an object in their detection range
- detects obstacles or objects in the way and avoids collisions
- e.g. parking assistance systems in vehicles
11
Q
temperature sensors and example [2]
A
- measure temperature of object or environment
- e.g. thermometers
12
Q
magnetic sensors and example [3]
A
- detect the presence or changes in magnetic fields
- measure magnetic forces or the position of magnetic objects
- e.g. compass in smartphones
