Arduino Water Level Sensor

this app can monitor the high level of water tank using arduino,Bluetooth module and real floating level sensor

hardware:
connect pin 2 of arduino to 1 terminal of sensor
connect gnd of arduino to 1 terminal of sensor
connect 5 volt of arduino to vcc of hc-06
connect gnd of arduino to gnd of hc-06
connect tx of arduino to rx of hc-06
connect rx of arduino to tx of hc-06


arduino code:



void setup() {
//start serial connection
Serial.begin(9600);
//configure pin 2 as an input and enable the internal pull-up resistor
pinMode(2, INPUT_PULLUP);


}

void loop() {
//read the pushbutton value into a variable
int sensorVal = digitalRead(2);
//print out the value of the pushbutton

if((sensorVal)!=0)
{
Serial.println(sensorVal);
delay(1000);
}



}
