- | Andurid on seadmed, mis teisendavad mingi füüsikalise suuruse, näiteks temperatuuri, valgustugevuse, | + | Sensors are devices converting any kind of physical attributes (temperature, luminance, force, acceleration etc.) to a understandable form for humans or machines. With the help from sensors the microcontroller receives information from the surrounding environment and makes decisions based on it. There are many types of sensors, approximately |
- | Analooganduris muutub füüsikalise suuruse muutudes mõni selle elektriline väärtus, tavaliselt kas pinge või takistus. Kuna mikrokontrollerid on digitaalsed seadmed, siis analooganduri info edastamiseks kontrollerile tuleb see digitaalseks teisendada. Selleks kasutatakse peamiselt mikrokontrolleritesse sisse ehitatud analoog-digitaalmuundureid. | + | In analogue sensor any change in physical attributes changes one of its electrical values, usually voltage, current or resistance. Since microcontrollers are digital devices, the signal have to be converted from analogue to digital before delivering it to controller. For this purpose analogue-digital converters are used which usually are built-in to the microcontroller. |
- | Kui analoogandur juba sisaldab info digitaliseerijat, nimetatakse seda digitaalseks anduriks. Peale digitaliseerimise võivad digitaalsed andurid infot ka normeerida, andurit kalibreerida ja palju muid funktsioone täita. Digitaalse anduri | + | Analogue sensor which already includes digitizer of information, it is called digital sensor. Digital sensors can also standardize information, calibrate sensors and perform a great deal of other functions. There are many ways for transmitting |
