I am trying to find out if I could identify objects based on their transmittance/reflectance properties. I have thought out two approaches for the same:
Ultrasonic sensor (HC SR04) - I have used this sensor for some of my projects but have been only able to get the Time-of-flight data from this sensor. Is there any method, I could measure the strength of the reflected wave?
RF module (433MHz) - These come in a pair of transmitter/receiver but I could not find any articles which could allow me to measure the strength of the received wave.
I am new to this topic so do forgive me if I have made some foolish mistake. Would I require additional components to do this or will it be possible with the original sensors itself?
Thank you so much for the help.
