Ultrasonic Distance Waterproof Sensor (27~800cm, ULA)
This ultrasonic distance sensor features a waterproof probe and operates based on echo-ranging principles, accurately measuring distances without physical contact. Its bell-mouth shell enhances ultrasound directivity and stability. The sensor offers RS232 and voltage analog output modes, switchable via a button. Notably, its default detection starting point differs from traditional methods, requiring adjustment for accurate readings.
