About Course

This course will talk about sensors and their fundamentals. Technology is not just for the design process but is becoming an integrative part of Landscape Architecture Design. Sensors represent a tremendous opportunity to augment sustainable design and behavior for environmental monitoring. They can be used for a wide variety of sustainable design uses. This course discusses the basics of sensors, how they work, the types of sensors, and how they can be used in the design.

A sensor is an electronic component or subsystem utilized for detecting modifications or events within its environment. A computer processor is one good example of sensor technology, also touch-sensitive elevator buttons known as tactile sensor. This innovation made a huge impact in the world of information and technology and almost every field or industry is using it for productivity and progress.

Course Content

Defination of Sensor
There are numerous definitions as to what a sensor is but I would like to define a Sensor as an input device which provides an output (signal) with respect to a specific physical quantity (input).

Temperature Sensor

Proximity Sensor
A proximity sensor is a non-contact sensor that detects the presence of an object (often referred to as the “target”) when the target enters the sensor’s field.

Accelerometer Sensor
An accelerometer is a device that measures the vibration, or acceleration of motion of a structure.

Infrared (IR) sensor
An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment

Pressure Sensor
To understand pressure sensors, first, you need to understand the pressure. Pressure is an expression of force exerted on a surface per unit area.

Light Sensor
The light sensor is a passive device that converts the light energy into an electrical signal output.

Ultrasonic Sensor
An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal.

Smoke, Gas and Alcohol Sensor
The MQ series of gas sensors utilize a small heater inside with an electrochemical sensor these sensors are sensitive to a range of gasses are used at room temperature.

Touch Sensor
Touch sensors work similar to a switch. When they are subjected to touch, pressure or force they get activated and acts as a closed switch. When the pressure or contact is removed they act as an open switch.

Color Sensor
A color sensor detects the color of the material. This sensor usually detects color in RBG scale. This sensor can categorize the color as red, blue or green. These sensors are also equipped with filters to reject the unwanted IR light and UV light.

Humidity Sensor
A humidity sensor (or hygrometer) senses, measures and reports both moisture and air temperature.

Magnetic Sensor
Magnetic sensor definition is a sensor which is used to notice disturbances as well as changes within a magnetic field such as strength, direction, and flux.
