Description
Perhaps please add a link in the readme to the forum at https://forum.arduino.cc/t/how-to-read-serial-data-from-non-contact-ultrasonic-liquid-level-sensor/507781 That forum has the most details I've found about this sensor, including links to translated spec sheet at https://forum.arduino.cc/uploads/short-url/pk5OOiweOxHfs993Dxte1S0yw4H.pdf and real-life tips, tests, and experiences.
