It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. The ultrasonic distance sensor HC-SR04 emits an ultrasonic wave from the trigger and it is received by the echo after deflecting an object. The length of the pulse is. I have successfully ran a program using arduino ide to verify that hc-sr04 module I am using works correctly. This may interfere with your stepper motor step timing. Ultrasonic ranging module HC – SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. Macnet Technology offering HC SR04 Ultrasonic Module For Arduino, Industrial Ultrasonic Sensor, Ultrasonic Distance Measuring Sensor, Ultrasonic Distance Sensor. For the interfacing example given below, P0. pdf That is where the. The HC-SR04 uses sound instead of light as the GP2D12 module does. It is perfect for the obstacle avoiding system in your robot project. Smaller intervals may work for short distance, but can give erroneous readings, e. This is the HC-SR04 ultrasonic distance sensor. This action will trigger an ultrasonic hc-sr04 ultrasonic sensor datasheet at frequency of 40Hz from the transmitter and the receiver will wait for the wave to return. Code for the HC-SR04 is similar, but uses 2 separate Arduino pins.
