Examples of Sensors and Transducers Flashcards
Senses the
temperature for example it gauges the change in the temperature
Temperature Sensor
The adjustments in the Temperature relate to change in its physical property like resistance or voltage
Temperature Sensor
Is a non-contact type
sensor that distinguishes the presence of an
article
Proximity Sensor
Uses of Proximity Sensor
Mobile Phones,
Cars (Parking Sensors),
enterprises (object arrangement),
Ground Proximity in Aircrafts,
automated doors,
self-driving cars,
toy cars,
automation systems,
Are sensors that measure the rate of change of speed. It measures the change in velocity per unit time
Accelerometer sensors
Are attached to an object to measure the vehicle dynamics and the orientation, tilt of the object
Accelerometer sensors
Is an electronic device that senses the infrared radiation in a surrounding area
IR or Infrared Sensor
2 Types of Infrared sensors
- active
- passive
Detects and emits radiation. It has a led which
emits the light and a receiver.
active IR sensor
The IR sensors have IR _____ and _____.
receiver, emitter
The _____ gives out infrared light while the
power is connected. The _____ is a
photodiode.
emitter, receiver
IR sensors can be used in applications such as:
gesture control,
line follower robot,
multi-touch control,
wireless remote and keyboard,
agricultural applications in drone,
etc.
Are sensors that produce an output voltage which is directly proportional to the pressure experienced by the object. These sensors are mounted on-board which are placed in the object under observation.
Pressure Sensors
Is also called a photoelectric device. It converts light into voltage.
light sensor
The most common light sensor
LDR or Light Dependent Resistor
Is a sensor that detects and identifies different types of gasses. Most of these sensors are used to detect gas leaks, carbon monoxide, and smoke. Commonly, Metal-Oxide based gas
sensors are used.
smoke sensor
Smoke sensor is also known as
chemiresistor
Function similarly to tactile switches which records and detect
physical touch
Touch sensors
Is a sensor that by detection of the ratio of intensity of the RGB light, the color of the object is identified. These sensors are used in true color recognition and color mark detection.
Color Sensor
Measures humidity. Humidity is one of the quantities that is sensed in electronic systems.
Humidity Sensor
2 Classification of humidity sensor
- relative and
- absolute
humidity sensor.
Measures humidity by comparing the reference humidity and measuring the temperature of the object then checks for the equivalent humidity in that given temperature
Relative humidity
Does not use reference temperature
Absolute humidity
Are devices that produce an electrical signal that varies with an angular movement. It has a rolling ball that goes to the bottom when to power of thecircuit is turned on which forms an electrical connection to the circuit.
Tilt sensors
