I need a sensor to detect the presence of an object on the other side of a plastic wall.
Originally I thought of using an ultrasonic sensor but the range I am working with is about 10mm. Most ultrasonic devices I have seen have a minimum range of 200mm, far too big.
Can anyone suggest another sensor? Or somewhere where I can get short range ultrasonic sensors.
Thanks
John
