    Weird characters in serial monitor

    Dear developers, I am simply using Serial.println(); command, but I get some weird characters in the serial port display window. Code : #include <Wire.h> // HIH6130 I2C address is 0x27(39) #define Addr 0x27 int tzero = 196; int tspan = 17; int hzero = 196; int hspan = 17; void setup() { Wire.setModule(1); Wire.begin(); pinMode(P1_3,OUTPUT); pinMode(P1_2,OUTPUT); pinMode(P1_6,OUTPUT); Serial.begin(9600); Serial.println("OK"); delay(300); } void loop() { unsigned int data[4]; // Start I2C Transmission Wire.beginTransmission(Addr); // Select data register Wire.write(0x00); // Stop I2C Transmission Wire.endTransmission(); // Request 4 bytes of data Wire.requestFrom(Addr, 4); // Read 4 bytes of data // humidity msb, humidity lsb, temp msb, temp lsb if (Wire.available() == 4) { data[0] = Wire.read(); data[1] = Wire.read(); data[2] = Wire.read(); data[3] = Wire.read(); } // Convert the data to 14-bits float humidity = ((((data[0] & 0x3F) * 256) + data[1]) * 100.0) / 16383.0; float temp = ((data[2] * 256) + (data[3] & 0xFC)) / 4; float cTemp = (temp / 16384.0) * 165.0 - 40.0; // Output data to serial monitor Serial.print("Relative Humidity :"); Serial.println(humidity); Serial.println(" %RH"); Serial.print("Temperature in Celsius :"); Serial.println(cTemp); Serial.println(" C"); Serial.println("=============================================================== "); int VcTemp = map(cTemp, -5, 125, tzero, tspan ); int vhumidity = map (humidity, 0, 100, hzero, hspan); analogWrite(P1_2, VcTemp); analogWrite(P1_6, vhumidity); delay(1000); } Serial Output : (in one single line, means it keeps printing these characters in just one line on and on.picture : Thax.
