Fundamentals Midterm Flashcards
These types of sensors measure the amount of water vapor in the atmosphere of air or other gases. are commonly found in heating, vents and air conditioning (HVAC) systems in both industrial and residential domains. They can be found in many other areas including hospitals, and meteorology stations to report and predict weather.
Humidity Sensors
Used to detect the light beam reflected from the target. A thru beam type
Photoelectric sensor
These types of sensors monitor and detect changes in air quality, including the presence of toxic, combustible or hazardous gasses.
Gas Sensors
Used to measure the change in light quantity caused by the target crossing the optical axis
Sensor
It is sensing the temperature in a house to determine when to tell the heating to turn on/off. This system is not just automated though, the temperature at which the heating will switch on or off can be adjusted.
Thermostat
The role of a sensor in a control and automation system is to __, providing this information to the control system.
detect and measure some physical effect
What are sensors made up of?
Ceramics
What are the two basic components of a photoelectric sensor?
Receiver and Emitter
Are used in a large range of industrial applications for generating information about various objects. without physical contact.
Optical sensors
A type of sensor is used to measure the change in light quantity caused by the target crossing the optical axis.
Thru-beam
Noncontact profilers cover a spectrum of techniques and methods and rely on different technologies to capture surface topography via a derived optical signal. Generally, these varied approaches incorporate an optical stand equipped with objectives, a digital camera, and scanner motor to efficiently capture full areas.
Optical profiler technology
Useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol.
Grove - Gas Sensor(MQ5)
These types of sensors measure the amount of water vapor in the atmosphere of air or other gases. are commonly found in heating, vents and air conditioning (HVAC) systems in both industrial and residential domains.
Humidity Sensors
These types of sensors sense characteristics in their surroundings by either emitting or detecting radiation. They can also measure the heat emitted by objects. Infrared sensors are used in a variety of different IoT projects including healthcare as they simplify the monitoring of blood flow and blood pressure
Infrared Sensors
It convert rays of light into electrical signals. There are many applications and use cases for optical sensors. In the auto industry, vehicles use optical sensors to recognize signs, obstacles, and other things that a driver would notice when driving or parking.
Optical sensors
Used to measure the change in light quantity caused by the target crossing the optical axis
Thru-beam sensor
Used in home heating ventilating and air conditioning systems offices, cars, industrial spaces and greenhouses
Temperature Sensor
Those sensor made from conventional (traditional) ceramic materials, typically very tough in nature, and those which are made up of
piezoceramic materials
Detect the amount of current passing through a conductor by measuring the magnetic field generated around it
Current Sensor
conduct electricity at a certain rate therefore leading to a specific level of charge flow that is associated with a specific level of pressure
Barometric Sensor
Measure the angular rate or velocity, often defined as a measurement of speed and rotation around an axis. Use cases include automotive, such as car navigation and electronic stability control (anti-skid) systems.
Gyroscope sensors
It detect an object’s acceleration i.e. the rate of change of the object’s velocity with respect to time. can also detect changes to gravity.
Accelerometers
Are used for non-contact detection of objects near the sensor. These types of sensors often emit electromagnetic fields or beams of radiation such as infrared.
Proximity sensors
A senses changes in gases and liquids. When the __ changes, the sensor detects these changes, and communicates them to connected systems. Common use cases include leak testing which can be a result of decay
Pressure sensor
Use how long it takes transmitted IR to be reflected back into the receiver to approximate its distance from an obstacle
IR Range Sensor
Measure presence o absence of an obstacle and measure how further away an object
ultrasonic range finders
