The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object – just like bats or dolphins do. This module offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). This module has stable performance and high-accuracy measurement distance. Comparable with SRF05 and SRF02 ultrasonic modules.
High precision and a full range of ranging programs: C51, PIC18F877, Ultrasonic LCD1602 display, Ultrasonic LCD12864 display, Digital tube display, Serial port display, Ranging reference program, etc.
