Hello,
Hey guys, can you help me how to use ultrasonic sensor(HC-SR04) as a receiver alone (transmitter is another ultrasonic sensor) and how to measure received signal strength?
Thank you.
Amplification, then peak-detection.
First, you will have to brought out analog signal, soldering skills is not an option.

Amplification is necessary for distances >1m
The problem is that ultrasonic sensor (HCSR04) is printing garbage values even the receiver didn’t receive any ping from transmitter. Is there any way to process those garbage values?
Kindly hep me out.
