JSN-SR04T / JSN-SR04T-V3.3 Ultrasonic Distance Measuring Transducer Sensor for Arduino

Product Description

The JSN-SR04T-V3.3 Ultrasonic Distance Measuring Sensor is a waterproof and highly reliable non-contact distance measurement module designed for Arduino and other microcontroller projects. It features temperature compensation, advanced co-frequency interference filtering, and a stable DC-DC design for accurate readings in harsh environments.

With a measurement range of 23 cm to 500 cm and accuracy up to ±1 cm (resolution 3 mm), this sensor is ideal for applications such as liquid level detection, sewer measurement, robotics, obstacle avoidance, and smart parking systems. The adjustable measurement angle makes it versatile for both narrow and wide detection scenarios.
