Features:

  • Operating voltage: DC 5V
  • Quiescent current: 5mA. Farthest distance: 4.5m.
  • The device is waterproof, but it couldn't work underwater. Please note it.
  • High accuracy, strong anti-jamming, small size, easy to use, low voltage, low power consumption.
  • Integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions.
Works well for the money. Haven't tested how waterproof it is.

Haven't used it long but it seems accurate enough. Only down to 20cm though. Still it should work for my use. Now to just program the arduino ond raspberry pi to display the results.

Cheap way to measure distances for some applications

Easy to integrate with particle photon. I'm using it to monitor the water level in a catchment tank.

Works!

Works good using 3.3v ESP32 with board programmed with Arduino IDE. Values are reliable past 10cm.
