Specification:
Stable performance, precise measure of distance. And can compare with SRF05, SRF02 Ultrasonic Ranging Module. Module precision, blind spots (2cm) super close, stable distance measurement!
Feature:
Voltage: DC5V
Quiescent current: less than 2mA
Level output: 5V high
Level of output: 0V low
Induction Angle: not more than 15 degrees
Detection distance: 2cm-450cm
High precision: better than 2mm
Wiring, VCC, trig 's (control side), echo (receiving end), GND
Note:
(1) IO trigger ranging to at least 10us high signal;
(2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
(3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return. Test distance = (time high * speed of sound (340M / S)) / 2
Package:
1pc HC-SR04 Sound Ultrasonic Range distance Sensor module for Arduino
