The Schematic:
When you build the circuit do not put R2 resistor in untill last, Start with a high value (around 100k) then power up the circuit with between 6 and 12 volts. with the trap open so the alarm would go off start trying smaller value resistors untill the alarm goes off.
In this schematic I used a 8 channel logic level converter but a two channel will work the best and save space on your board.

HC-06 or HC-05 Bluetooth Board.
THE ARDUINO SKETCH:
(remember to disconnect the bluetooth board or its power before uploading the sketch.)
int val;
void setup() {
Serial.begin(9600);
}
void loop() {
val = analogRead(A7);
if (val>100)
{
Serial.println(“YOU GOT A MOUSE”);
}
else
{
Serial.println(“TRAP IS ARMED”);
}
delay(10000);
}
