Ultrasonic Liquid Level Monitoring Sensor

This ultrasonic level sensor, designed for liquid level detection applications, addresses common pain points of traditional ultrasonic sensors, such as large blind zones, wide measurement angles, slow response, and inconvenient installation. This sensor achieves a breakthrough by realizing an extremely small standard blind zone of 1.5cm and supports flexible setting of the maximum measuring range from 30 to 300cm via commands (factory default is 200cm). The sensor features a miniature dustproof and waterproof structure with an IP67 protection rating. It supports a wide voltage input of 3.3V to 12V and integrates electrostatic discharge (ESD) protection devices compliant with IEC61000-4-2 standards (with anti-ESD up to +4K/8K) at the input/output interfaces, ensuring extremely high reliability during harsh temperature cycling from -25℃ to +65℃.
