Arduino Tank Monitor

1// This routine let you to monitor level in two tanks:
2// Standard  protocol to select instruments:
3 void SendString(byte InstrNr, int MW) { 
4Serial.print('#');
5Serial.print(InstrNr);
6Serial.print('M');  
7Serial.print(MW); Serial.print('<'); }
8void setup() {
9  // initialize  serial communication at 9600 bits per second:
10Serial.begin(9600);
11}
12//  the loop routine runs over and over again forever:
13void loop() {
14  // read  the input on analog pin 0:
15  int sensorValue0 = analogRead(A0);
16   // read  the input on analog pin 1:
17  int sensorValue1 = analogRead(A1);
18  // Convert  the analog readings (which goes from 0 - 1023) to a level value(0 - 100%):
19  float  voltage0 = sensorValue0 * (100.0 / 1023.0);
20  float voltage1 = sensorValue1 *  (100.0 / 1023.0);
21    // print out the value you read:
22SendString(2,voltage0);  // Instrument #02 - Vert Meter
23SendString(3,voltage1); // Instrument #03 - Vert  Meter
24SendString(41,voltage0); // Instrument #41 - Num Display
25SendString(42,voltage1);  // Instrument #42 - Num Display
26SendString(90,voltage0); // Instrument #90 -  Min Trend
27SendString(91,voltage1); // Instrument #91 - Min Trend
28delay(100);
