Kawm yuav ua li cas siv los sis cuam tshuam infrared sensors nrog Arduino.This yog pib phau ntawv qhia IR sensors .
Lub infrared sensor lossis infrared sensor muaj ob lub ntsiab qhov chaw.Infrared transmitter thiab infrared receiver. Txoj hauj lwm ntawm infrared transmitter los yog infrared transmitter yog xa cov infrared tsis, thaum txoj hauj lwm ntawm qhov infrared receiver yog tau txais cov teeb tsis muaj infrared. Lub infrared receiver xa cov ntaub ntawv tsis tu ncua mus rau Vout tus pin ntawm lub sensor nyob rau hauv daim ntawv ntawm 0 los sis 1 .
Yog hais tias muaj ib qho khoom nyob rau hauv pem hauv ntej ntawm infrared sensor, infrared yoj emitted los ntawm infrared transmitter yuav reflected los ntawm tus kwv thiab tau txais los ntawm infrared receiver. Hauv qhov no, lub infrared sensor muab 0.Tiam sis, yog tsis muaj khoom nyob rau hauv pem hauv ntej ntawm infrared sensor, infrared tsis emitted by infrared transmitter yuav tsis tau txais los ntawm infrared receiver.Nyob rau hauv cov ntaub ntawv no, lub infrared sensor muab 1 .
Kev xav ntawm ib qho IR sensor:
1) Av
2) 5 volt
3) Pab kom
4) Vout
