}
else{

sleep();
}
}

mySwitch.send(10109000, 24); //low battery code

}Is this code any good??
It suppose to be a door sensor that should send the state signal and then goes to sleep and wakes again when the interrupt pin changes.
I am not able to send the close command when i shut the door.
please help me :)
