AN-1050 Ultrasonic Rangefinder

This design is a controller for an ultrasonic rangefinder. This design is based on the HC-SR04 – ultrasonic sensor module. The HC-SR04 ultrasonic sensor module functions like sonar to determine distance to an object, as bats or dolphins do. It offers excellent non-contact range detection with high accuracy and stable readings. The distance of sensing is from 2cm to 400 cm (1 to 13ft.). Its operation is not affected by ambient light or optically non-reflective material, although acoustically absorbent materials like thick cloth can be more difficult to detect. The module contains both ultrasonic transmitter and receiver.
