Servomotor SG90 360 grade, continuu

Servo motor tip SG90 cu rotatie la 360 grade, greutate 9grame, ideal pentru aplicatii RC.

Rotatia este continua si nu se poate controla pozitia exacta a servomotorului la un anumit grad. Prin "servo.write" se stabileste directia si viteza de rotatie a servomotorului.

Specificatii:

Tensiune alimentare: 3 - 7.2VDC

Viteza functionare: 0,12 s/60o (la 4,8V)

Cuplu in blocare: 1Kg/cm la 4.8V

Dimensiuni mm: 22 x 11.5 x 22.5

Include diferite estensii brat si suruburi de fixare

Exemplu cod test pentru servomotor:

// zoomkat 3-28-14 serial servo incremental test code

// using serial monitor type a character (s to increase or a

// to decrease) and enter to change servo position

// (two hands required, one for letter entry and one for enter key)

// use strings like 90x or 1500x for new servo position

// for IDE 1.0.5 and later

// Powering a servo from the arduino usually *DOES NOT WORK*.

#include<Servo.h>

String readString;

Servo myservo;

int pos=1500; //~neutral value for continous rotation servo

//int pos=90;

void setup()

{

myservo.attach(9, 400, 2600); //servo control pin, and range if desired

Serial.begin(9600);

Serial.println("serial servo incremental test code");

Serial.println("type a character (s to increase or a to decrease)");

Serial.println("and enter to change servo position");

Serial.println("use strings like 90x or 1500x for new servo position");

Serial.println();

}

void loop()

{

while (Serial.available()) {

char c = Serial.read(); //gets one byte from serial buffer

readString += c; //makes the string readString

delay(2); //slow looping to allow buffer to fill with next character

}

pos = readString.toInt();

}

if(readString =="a"){

Senzor MQ4 folosit pentru detectarea gazelor naturale si a metanului.

Specificatii:

Senzorul de gaz este Dioxidul de Staniu (SnO2) cu conductivitate scazute in aerul curat.

Tensiune alimentare: 5VDC, 150mA

Concentratie detectata: 300 - 10000ppm

Output: Pin Digital sau pin Analogic

Iesire Analogica: 0 - 5V; voltajul creste sau scade in functie de concentratia detectata

Iesire Digitala TTL

Exemplu cod citire analogica:

void setup() {

  // initialize serial communication at 9600 bits per second:

  Serial.begin(9600);

}

// the loop routine runs over and over again forever:

void loop() {

  // read the input on analog pin 0:

  int sensorValue = analogRead(A0);

  // print out the value you read:

  Serial.println(sensorValue);

delay(1);        // delay in between reads for stability

}

Specificatii:

Rezistenta excelenta la interferenta cu Alcool si fum

Tensiune alimentare: 5VDC, 150mA

Output: Pin Digital sau pin Analogic

Iesire Analogica: 0 - 5V; voltajul creste sau scade in functie de concentratia detectata

Iesire Digitala TT

Exemplu cod citire analogica:

void setup() {

  // initialize serial communication at 9600 bits per second:
