Widely used Sweepers, DIY robot cars, for raspberry pi project,It can be building a little robot to measure distances in a room under construction. HC-SR04 Ultrasonic Sensor Module It measures distance by sending out a sound wave at a specific frequency and receiving back that sound wave to bounce. Good Accuracy Power Supply 3V-5.5V DC, Detection angle 15 , Minimum target distance is 2.0cm from the end of the Voltage transducers. Maximum repeatable target distance is 2CM-150CM for a large unobstructed stationary target. Easy to install There are 4 pins out of the module, VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output, So it's a very easy interface for controller to use it ranging. Note The module should be inserted in the circuit before been powered to avoid producing high level of Mis-operation.
