Enhanced Accuracy and Range: Experience precise distance measurements with our JSN-SR04T module, boasting a maximum range of 5 meters (16.4 feet) and a minimal blind zone of 25cm. Ideal for projects requiring accurate spatial data, this sensor operates on a 5V DC power supply and includes a 2.5m (8.2ft) lead. Compact and Ready-to-Use: Each ultrasonic sensor measures 41mm (L) x 28.5mm (W), ensuring a compact fit for space-sensitive applications. The package comes with four fully-equipped modules, each with integrated wiring, ready for immediate deployment in your projects. Robust Design for Challenging Environments: Built to withstand harsh conditions, the JSN-SR04T features a closed-line probe that enhances its anti-interference capabilities, making it suitable for humid environments. Note: It is not designed for underwater use or prolonged water immersion. Versatile Applications: The JSN-SR04T is perfect for a variety of applications including horizontal distance measurement, obstacle avoidance, traffic control, security systems, industrial automation, and educational projects, offering reliable performance in both professional and academic settings. Simple Integration with Your Projects: Wiring this module is straightforward with clearly marked connections: +5V (Power Positive), Trig (Control Pin) RX, (Receive Pin) TX, and GND (Power Negative). This setup ensures easy integration into your existing projects or any compatible microcontroller systems.
