Description

Ultrasonic ranging module HC-SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit. If you are sourcing for an ultrasonic ranging module, the HC-SR04 is a good choose. Its stable performance and high ranging accuracy make it a popular module in electronic market. Compared to the Shap IR ranging module, HC-SR04 is more inexpensive than it. But it has the same ranging accuracy and longer ranging distance.
