Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor for Arduino
Main technical parameters:
Voltage: DC 5V Static current: less than 2mA Electrical level output: 5V high Electrical level output: at the end of 0V Induction angle: not more than 15 degrees Detection distance: 2cm-450cm High precision: 2mm Wiring: VCC, trig (control side), echo (receiving end), GND
Module works: Using IO trigger distance, the high signal to at least 10us module automatically sends eight 40khz square wave, automatically detects whether a signal return; 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
This module performance is stable, measure the distance accurately. performance nearly the same as SRF05, SRF02 SRF05, SRF02 ultrasonic distance measuring module and other comparable. Module High precision, blind spots (2cm) super close.
