Tangyy 5pcs HC-SR04 Ultrasonic Sensor, Distance Sensor with Ultrasonic Transmitter and Receiver Module fit for Raspberry Pi,MEGA2560, Robot (Blue)
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: 003c15 °, 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.
