Description

HC-SR04 Ultrasonic Sensor Distance Measuring Module

This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.

– Model: HC-SR04
– Color: Blue + Silver
– Working voltage : 5V(DC)
– Static current: Less than 2mA.
– Output signal: Electric frequency signal, high level 5V, low level 0V.
– Sensor angle: Not more than 15 degrees.
– Detection distance: 2cm~450cm.
– High precision: Up to 3mm
– Mode of connection: VCC / trig(T) / echo(R) / GND
– Module Working Principle:
– Adopt IO trigger through supplying at least 10us sequence of high level signal
– The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal
– If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving.
