Fig. 4: Timing diagram of ultrasonic sensor. Compile and upload this code to Arduino Uno. Open Serial Monitor under Tools of Arduino IDE to see the sensor output (distance between sensor and object).

I didn’t use the transformer secondary as implied in the schematic diagram though. Instead I just connected the ultrasonic transducer across the primary, so a simpler center-tapped inductor would be ...

The module, the IA-UWM-2-GP30-DN20 from Chinese metering equipment manufacturer iESLab, is based on the ams TDC-GP30 ultrasonic flow sensor chip. The TDC-GP30 performs precise timing measurements and ...
