JSN-SR04T Waterproof Ultrasonic Sensor Module 4.5m Range

The JSN-SR04T Waterproof Ultrasonic Sensor Module is an industrial-grade rangefinder designed for accurate distance measurement in wet or harsh environments. It features a 40 kHz ultrasonic probe capable of measuring distances from 25 cm up to 4.5 m with a resolution of approximately 0.5 cm and an angle of less than 50°. The module operates at DC 3.3–5 V with a working current of 30 mA and is compatible with HC-SR04 code and interfaces. Its compact size of 41 × 28.5 mm allows easy integration in horizontal ranging, obstacle avoidance, automated control, traffic monitoring, security, and educational projects.
