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.

Features:

1. High Degree of Protection: The enclosed waterproof probe ensures durability in various environments.
2. Wide Power Supply Range, Low Power Consumption: Compatible with 5V to 12V supply voltage, with efficient power usage.
3. High Measuring Accuracy and Resolution: Provides precise distance measurements with a resolution of 1mm.
4. High-Precision Temperature Output and Compensation: Includes temperature output and compensation function for accurate readings in varying temperatures.
5. Great Output Compatibility: Offers both RS232 and voltage analog output modes for versatile integration into different systems.
