Product description
Sensor ini membaca jarak 2cm sampe 450 cm, akurasi 3mm. Prinsipnya, agan kirim pulsa HIGH ke pin TRIGGER selama 10us-20us. Nanti akan muncul pulsa HIGH di pin ECHO selama t detik. Nah jaraknya berarti: jarak = t * 340 / 2
*) 340m/s adalah kecepatan suara, dibagi 2 soalnya sinyal ultrasoniknya mesti bolak-balik
