kuman 5pcs Hc-sr04 Ultrasonic Distance Measuring Sensor Module kit for Arduino UNO Mega R3 Mega2560 Duemilanove Nano Raspberry Pi 3 Robot K18

Description

Feature:
There are 4 pins out of the module: VCC , Trig(control side), Echo(receiver),out (empty) GND .So it s a very easy interface for controller to use it ranging.
The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance,it will take the different duration of high level. So we can calculated the distance easily:
The test distance = (Duration of high level * speed of sound (340M/S))/2

Module details:
Voltage: DC5V;
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 0.3cm;

Package includes:
5* HC-SR04 Ultrasonic Distance Sensor
