Ultrasonic Module HC-SR04 Distance Measuring Ranging Sensor for Arduino
This module has stable performance and accurate measurement distance.
Detection distance: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm); Detection angle: <15 °.
HC-SR04 for Arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
This module is fully Compatible with GH-311 anti-theft module.
