In order to measure the distance of the colored paper sheet from the sensors we use the HC-SR04

ultra-sonic distance sensor.

As can be seen from the photo, the modules has 4 connections:

Vcc, which is 5V
Gnd
Trig
Echo

The module is triggered with a 10us TTL trigger pulse. It then sends an 8 cycle sonic burst of 40 kHz and tries to detect the echo. The module sends an echo pulse whose length is proportional to the time the sound signals takes to the target and back.
