Hello,
I am working on a project (not a college project but in production)that requires an object to be sensed at the distance of 10 cm to 20 cms when placed under the sensor. For this I have decided to use a diffuse reflection sensor.
Now, if I am going in the market asking this sensor unit which comes in an attractive package is simply bursting my budget to the value one can never think of.. So I have decided to make my own sensor.. I have decided to use a simple IR trasmitter/receiver pair to couple it with 555 timer.. Is that a good way to make a long lasting and reliable unit?
BY the way, Just to explain the logic of operation, An object comes into the sensing zone and an output goes high at IR receiver.. Output here onwards stays ON.. It goes OFF if the object is removed from the sensing zone.. Any ideas regarding how can I manage to make a circuit simple and reliable?
Thanks.
