JSN SR04T Ultrasonic Distance Sensor by WWZMDiB Waterproof Module

Description

Product Overview

The WWZMDiB JSN SR04T ultrasonic distance measuring sensor transducer module is engineered for precision and durability. It features a fully sealed waterproof emitter that protects the acoustic components from moisture, dust, and harsh environmental conditions, ensuring consistent performance even in demanding industrial settings. Operating on a flexible voltage range of 3 to 5.5 volts, the module integrates seamlessly with a variety of microcontroller platforms, including Arduino, Raspberry Pi, and ESP series boards. Its compact dimensions of 1.61 x 1.61 x 1.12 inches and lightweight design (2.4 ounces) make it easy to mount in confined spaces while maintaining a robust structural integrity.

The sensor delivers a measuring range from 25 centimeters up to 4 meters, with a detection angle of 75 degrees and a precision of 2 millimeters. This combination of range and accuracy enables reliable distance detection for applications such as obstacle avoidance, level sensing, and proximity monitoring. The module’s ultrasonic transducer operates at a frequency of 40 kHz, providing rapid response times and stable echo detection across varied surface textures. Detailed specifications include a working voltage of DC 3‑5.5V, a current consumption of less than 30 mA during active measurement, and a typical echo pulse width of 150 µs at the minimum range.

Usage

The JSN‑SR04T is ideally suited for a broad spectrum of industrial and hobbyist projects. In robotics, it serves as a core component for autonomous navigation, enabling robots to detect obstacles and adjust their path in real time. For automotive applications, the sensor can be employed as a reverse‑parking aid, providing drivers with audible or visual alerts when approaching an object. In manufacturing environments, it assists in material handling systems by monitoring the presence and distance of items on conveyor belts, thereby improving safety and efficiency.

Outdoor installations benefit from the sensor’s waterproof construction, allowing it to function reliably in rain, fog, or dusty conditions. It can be integrated into smart irrigation systems to measure water levels in tanks or reservoirs, triggering pumps when thresholds are reached. Additionally, the module is compatible with security alarm systems, where it can detect unauthorized entry by measuring sudden changes in distance.

The sensor’s low power consumption and simple serial interface (UART) make it a perfect fit for battery‑powered devices and IoT gateways. Developers can quickly prototype with readily available libraries, reducing time‑to‑market for innovative solutions.
