I need a sensor recommendation. I need a very small sensor that is able to sense an object...the foot print of the sensor shouldn't be no wider than 10 centimeters. LDR/IR is out of the question. It should be like break beam however those need a collector on the other side don't they? Time of flight is ideal because light and distance aren't an issue. In short I need a sensor that is small and basically states...high/low..object sensed no matter if it is black, white, yellow etc. and has a good range. Outside time of flight is there such a sensor? motion detector? Looking for suggestions. Thanks!
yes those would work however I am stuck on the height of the sensor. My project is placing a sensor in a nerf gun magazine clip. The nerf gun is one of those auto blaster types you hold the trigger and it shoots the darts....however when the last dart is shot I want to shut the motor off automatically. I am trying to eliminate holding the trigger in order to fire the darts...the one touch let it go type of thing. Then sensor would be located in each magazine clip....I can fit a arduino pro mini...a battery just fine...now just need a flush mounted detector to make it all work...clip and go.
