JSN-SR04T Waterproof Ultrasonic Sensor Module – 4.5m Range

Description

Description

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 40kHz ultrasonic probe capable of measuring distances from 25cm up to 4.5m with a resolution of approximately 0.5cm and an angle of less than 50. The module operates at DC 3.35V with a working current of 30mA and is compatible with HC-SR04 code and interfaces. Its compact size of 4128.5mm allows easy integration in horizontal ranging, obstacle avoidance, automated control, traffic monitoring, security, and educational projects.
