HC-SR04 Ultrazvucni merac udaljenosti.
Main technical parameters:
1: Voltage: DC 5V
2: Static current: less than 2mA
3: Electrical level output: 5V high
4: Electrical level output: at the end of 0V
5: Induction angle: not more than 15 degrees
6: Detection distance: 2cm-450cm
7: High precision: 2mm
Module works:
(1) using IO trigger distance, the high signal to at least 10us;
(2) module automatically sends eight 40khz square wave, automatically detects whether a signal return;
(3) a signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return. Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2;
