5 * Ultrahangos HC-SR04 távolságérzékelő modul és 3 * tartókonzol Arduino UNO Mega R3 Mega2560 Rapsberry Pi 3 Robot XBee számára
5*Ultrasonic HC-SR04 Distance Sensor Module & 3*Mounting Bracket For Arduino UNO Mega R3 Mega2560 Rapsberry Pi 3 Robot XBee
Feature :
HC-SR04 Ultrasonic Sensor
Power Supply :5V DC
Quiescent Current : <2mA
Effectual Angle: <15°
Ranging Distance : 2cm - 500 cm
Resolution : 0.3 cm
Output Signal: Electric frequency signal, high level 5V, low level 0V
Mode of Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.)
Ultrasonic Sensor Module Working Principle
Pull the Trig pin to high level for more than 10us impulse, the module start ranging.
The module automatically sends eight 40KHz square wave to detect whether a signal is returned.
Finished 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 distance = ((Duration of high level)*(Sonic :340m/s))/2. Distance L = 1/2 × T × C
Product Package:
5 X HC-SR04 Ultrasonic Sensors
3 X HC-SR04 Mounting Bracket
10 X Female-Male Dupont Cables
10 X Female-Female Dupont Cables
Note:
The module should be inserted in the circuit before been powered to avoid producing high level of misoperation; if producted, power it again.
The module is not suggested to connect directly to electric, if connected electric, the GND terminal should be connected the module first, otherwise,it will affect the normal work of the module.
When tested objects, the range of area is not less than 0.5 square meters and the plane requests as smooth as possible, otherwise ,it will affect the results of measuring.
