An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effe...
a lightbulb that connects to an app is an IoT device; however, how the lightbulb gathers data from its surroundings about your preferences and acts accordingly is where ambient computing comes in.
Another advantage with WWH is the expansion of information contained in a fault. Currently, OBDII uses a two-byte diagnostic trouble code (DTC) to indicate when a fault occurred (for example, P0070 indicates Ambient Air Temperature Sensor “A” has a general electrical failure). Unified Diagnost...
Sensor data is the output of a device that detects and responds to some type of input from the physical environment. The output may be used to provide information to an end user or as input to another system or to guide a process. Sensors can be used to detect just about any physical ...
Electrochromism refers to a color change in a substance that results when an electric current is applied. The change is reversible. An electrochromic rear-view mirror is one that automatically dims when it senses light from behind the car, thereby reduci
that converts physical events or characteristics. an actuator is a physical device– for example a switch or a valve– that converts electrical signals into physical events, for example air conditioning. in smart environments, sensor data is uploaded to cloud databases and data lakes where it is...
“Air quality” refers to the condition of the air within our surrounding. Good air quality pertains to the degree which the air is clean, clear and free from pollutants such as smoke, dust and smog among other gaseous impurities in the air.
To achieve a very sharp roll-off (“damping”) we need ahigh-order filter. This leads us to filter in the digital domain as opposed to the analog, however, digital filtering cannot be used to prevent aliasing. You can learn more about this in theWhat is an A/D converter. ...
If your motherboard temperature is above 80C, it might start to worry you a little, but fret not, it really hasn’t crossed danger territory. Much of both your idle and load temperatures will depend on factors like your ambient room temperatures, airflow in your case, the hardware you’re...
The way an ambient light sensor works, the light spectrum is narrowed so that only forms of light visible to the human eye are detected. That light is translated into a digital signal and fed to the processor inside the band. UV sensors ...
