    hello guys, i need your help badly...

    do u have any idea what is possible application for proximity sensor??

    shower using proximity sensor,that it will sense the hand of the person in the bath then the shower will flow but i dont know how will the circuit it be???

    please help any proposal for proximity sensor ??thanks

    How about automatically braking a delivery robot so it doesn't run into a human? How about alerting you to the presence of a wall/object close to a bumper of your car? A fathometer can be handy to a ship in shallow water.

    So far, bathroom sensors seem to be IR. Might not work in a shower because the hot water might never shut off. Do you want to be hit with a stream of cold water and stand there shivering while the hot water gets to the shower head?

    As beenthere already told there are a lot of sensors and applications.
    Here is a lot of information on sensors:
    And other sensors of all kinds:

    Sensors: Capacitive sensors Inductive sensors Piezo Displacement sensors Infra red sensors Pressure sensors Temperature sensor types Encoders and resolvers Magnetoresistive sensors Reed switches Thermocouple General overview Miscellaneous Temperature: PT100-RTD Tilt Sensors Hall sensor Optical sensors Temperature sensors Ultrasonic sensors

    For information on robotics and sensors, take a look at this page:

    Ideally proximity sensor is use to sense metal part only.
    Eg:- Use proximity sensor detect metal loading part present
