Water level monitoring system using Xbee

jremington:
Use the function atoi() to convert zero terminated character strings to an int.

If the transmitter is sending byte values, just use them as is. Post the transmitter code, using code tags ("</>" button).

Thanks for your reply!

Here's my code for the transmitter side:

const int trigPin = 11;
const int echoPin = 10;

// defines variables
long duration;
int distance;

void setup() {
  pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
  pinMode(echoPin, INPUT); // Sets the echoPin as an Input
  Serial.begin(9600); // Starts the serial communication
}

void loop() {
  // Clears the trigPin
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  
  // Sets the trigPin on HIGH state for 10 micro seconds
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  
  // Reads the echoPin, returns the sound wave travel time in microseconds
  duration = pulseIn(echoPin, HIGH);
  // Calculating the distance
  distance = ((duration * 0.034 / 2) * 10);
  
  // Prints the distance on the Serial Monitor
  delay(3000);
  Serial.println(distance);

}

I directly connected the rx and tx of xbee to rx and tx pins of arduino respectively. With this, it automatically transmit the readings to another xbee.

Can u suggest some codes for using the atoi? I am really new to coding in arduino. Thanks!
