TX:

Driven directly through the epoxed transducer desoldered from the hc-sr04

  • Amplitude: 12Vpp
  • Frequency: 58kHz
  • Number of cycles in burst: 3
  • Frequency of burst: 30Hz

RX:

The signal from the other desoldered transducer Amplified by 100 with two inverting offset amplifiers

Results

Top of bucket

About 175mm into bucket
