I have designed a Simple Circuit Diagram. I am going to ask for the comments from my EE friend.
After I have asked my EE friend, he asked my circuit needs to
add a Relay. It is an electrically operate switch. It is needed to connect with the mist machine. After the circuit recieved the signal from the distance sensor, the signal will be passed to the mircocontroller. If the signal is positive, the Relay would switch on. If not, the Relay would swtich off. It is more safe and stable for my circuit.
