Autobotix WATERPROOF ULTRASONICSENSOR-SR04

The Waterproof Ultrasonic Sensor SR04 (JSN-SR04T) is a high-performance distance measuring module designed for accurate non-contact distance detection in wet and harsh environments. Unlike the standard HC-SR04, this sensor comes with a waterproof ultrasonic probe, making it ideal for outdoor projects, water level monitoring, obstacle detection, robotics, parking systems, and industrial automation applications. It operates using ultrasonic sound waves at 40kHz frequency to measure distances with reliable accuracy. The module is compatible with popular microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, and other development boards. Its compact design, low power consumption, and strong anti-interference capability make it suitable for both beginners and professional electronics projects.
