2x 16mm 40KHz Ultrasonic Sensor Transceiver Probes - Waterproof, For Arduino/Projects

Working on a distance measuring project, a robot, or maybe a liquid level sensor?

These 16mm ultrasonic sensors are just what you need.

You get two of them in this pack.

They're integrated transceivers, meaning each probe can both send and receive the 40KHz ultrasonic signal.

They're waterproof, which makes them way more versatile for outdoor or industrial tinkering.

Just the bare sensors, ready to be wired up to your microcontroller like an Arduino or Raspberry Pi.

They're a generic unbranded component, but they're new and should work great for all kinds of maker projects.

If you need to measure distance without touching something, these little guys are the ticket.
