Dear Experts,
I bought a pair of infrared LEDs (transmitter + receiver).
I read that infrared can be used as distance sensor.
I have seen projects using it (eg. Sharp GP2D120 sensor) for robotics and toy cars. Just to clarify, I am not using the Sharp sensor but a normal infrared LED pair bought from an electronics parts store.
I tested it and measured with volt meter and it seems that different materials or objects reflect different intensity of infrared to the receiver.
I am wondering how can this be used as Distance sensor when there is no consistent voltage when sensing different materials.
Are there Infrared sensors that can measure distance accurately for different materials like wood, metal, plastic, concrete surfaces or materials?
Has anyone tried the Sharp sensor before? There are a few models of it.
At the moment, based on my testing , it fail to see how infrared led can measure distance accurately.
So, could you please help clarify my doubts.
Thank you very much.
Best regards
Ramone
