Sem 7 : Week 4

This is week 4 already .. My progress is i meet my SV to calibrate each sensor and build a coding for each sensor..


There is my progress for this week ..

void setup() {
  Serial.begin(9600); //Baud rate: 9600
}
void loop() {
  int sensorValue = analogRead(A0);// read the input on analog pin 0:
  float voltage = sensorValue * (5.0 / 1024.0); // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  Serial.println(voltage); // print out the value you read:
  delay(500);
}

🔺 this is coding for turbidity sensor .

Testing of Arduino Uno 

Calibrate of temperature sensor .

#include <OneWire.h>

#include <DallasTemperature.h>

// Data wire is plugged into pin 3 on the Arduino

#define ONE_WIRE_BUS 5

// Setup a oneWire instance to communicate with any OneWire devices

OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.

DallasTemperature sensors(&oneWire);

// Assign the unique addresses of your 1-Wire temp sensors.

// See the tutorial on how to obtain these addresses:

// http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html

DeviceAddress insideThermometer = { 0x28, 0xFF, 0xA7, 0x03, 0x81, 0x17, 0x05, 0xD6 };

void setup(void)

{

  // start serial port

  Serial.begin(9600);

  // Start up the library

  sensors.begin();

  // set the resolution to 10 bit (good enough?)

  sensors.setResolution(insideThermometer, 10);

  

}

void printTemperature(DeviceAddress deviceAddress)

{

  float tempC = sensors.getTempC(deviceAddress);

  if (tempC == -127.00) {

    Serial.print("Error getting temperature");

  } else {

    Serial.print("C: ");

    Serial.print(tempC);

    Serial.print(" F: ");

    Serial.print(DallasTemperature::toFahrenheit(tempC));

  }

}

void loop(void)

{

  delay(2000);

  Serial.print("Getting temperatures...\n\r");

  sensors.requestTemperatures();

  Serial.print("Inside temperature is: ");

  printTemperature(insideThermometer);

  Serial.print("\n\r\n\r");

} 

🔺 Coding for temperature Sensor..



Thats all my update for this week.. thank you.
