    Tương thích với cảm biến siêu âm HC-SR04, có LED hiển thị.

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics.

As you might have noticed, the most popular version of the module (comprised of an ultrasonic transmitter, ultrasonic receiver, and control electronics) has four interface pins — Vcc (5 V), Gnd (0 V), Trigger (Pulse In), and Echo (Pulse Out).

The operating current of the module is about 15 mA at 5-V DC input, and its operating frequency is 40 KHz. The measuring range of the module is in the 2- to 400-cm range with a measuring angle of 15°.
