รายละเอียดของสินค้า Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor 5V

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.
Features
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
Package includes
