http://e-learning.filippopigozzo.it/mod/resource/view.php?id=171 WebNov 15, 2016 · HC-SR04 specifies 5V at source. With a 5V board, digital pins have enough voltage to drive it. When you operate at 3.7V, it will barely operate if VCC goes straight to the sensor; but voltage drop on a digital pin makes the sensor unstable. (BTW, HC-SR04 specifies 15mA working current; 2mA is "Quiescent".) WebAccording to the datasheet of hc-sr04, the following is required to be done :-Keep the Trig pin HIGH for at least 10us; The Module will now send 8 cycle burst of ultrasound at 40 kHz and detect whether there is a pulse signal back; IF the signal returns, module will output a HIGH PULSE whose width will be proportional to the range of the object. tarian mojang priangan
