    Arduino Water Pollution Monitor

    Arduino: 1.9.0-beta (Windows 10), Board: "Arduino/Genuino Uno"C:\Users\Murty\Documents\Arduino\libraries\blink\water_purity_sensor\water_purity_sensor.ino: In function 'void loop()':water_purity_sensor:13:42: error: invalid operands of types 'const char [20]' and 'float' to binary 'operator+' Serial.println("The Conductivity is" + voltage);//print the correct reading to the serial port ^exit status 1invalid operands of types 'const char [20]' and 'float' to binary 'operator+'This report would have more information with"Show verbose output during compilation"option enabled in File -> Preferences.shows this errorplease help

    can anyone please tell me what is the problem with thisint conductivitySensorValue;// innitialise an integer variable value to hold sensor readingvoid setup() { Serial.begin(9600);//start serial communication so that we can print the reading out}void loop() { conductivitySensorValue = analogRead(A0);// get the integer representation of the sensor reading float voltage=0.0; voltage = conductivitySensorValue*(5.0/1023.0);// put the data in terms of voiltag (5 volts) Serial.println("The Conductivity is" + voltage");}

    You should give some modificationsThanks
