Waterproof Ultrasonic Ranging JSN-SR04T 2.0

Ultrasonic sensors, also known as sonar sensors, are ideal for detecting distance using sound waves. They feature two main channels: a trigger that emits ultrasonic pulses and an echo that listens for the reflected signal. By measuring the time it takes for the sound to return, the sensor calculates distance accurately—up to 4.5 meters (4500mm). It operates on a 5V power supply with a working current of 30mA and an idle current of just 5mA. Emitting sound at 40kHz, this sensor includes a waterproof transducer, making it suitable for outdoor use, though the main circuit board should still be protected from water.

This sensor is great for distance-based applications like water level monitoring, obstacle detection, and automated parking systems. Its waterproof sensing head allows placement in rugged or outdoor environments where traditional sensors may fail. Designed for compatibility with Arduino, it offers reliable performance with simple integration. Whether you're building a smart automation project or an industrial measurement system, this ultrasonic sensor provides durability, accuracy, and ease of use.
