Description

The JSN-SR04T-2.0 ultrasonic sensor utilizes a time-of-flight (ToF) principle, emitting 40 kHz sound pulses and measuring the echo return time to calculate distance. Its primary advantage is the physical separation of the sensing element and control electronics. The transducer is housed in a waterproof, sealed probe, allowing it to be placed directly in challenging environments while the control board remains in a protected location.

This design enhances durability for applications requiring sensing in moisture-prone areas. The module interfaces via a simple digital pulse protocol: a 10µs high pulse on the TRIG pin initiates a measurement cycle, and the ECHO pin outputs a high-level pulse whose duration is proportional to the measured distance. This standard interface ensures compatibility with a wide range of microcontrollers and single-board computers.

Key Features

  • Industrial-grade waterproof construction with a separate, sealed ultrasonic transducer probe.
  • High-accuracy distance measurement with a resolution of 0.5 cm across a 25 cm to 450 cm range.
  • Low power consumption with an average operating current of 30 mA at 5V DC.
  • Robust 2.5-meter cable provides flexibility for remote probe placement.
  • Wide operating temperature range from -10°C to +70°C for reliable performance in varied climates.
  • Compact and lightweight control board (41mm x 28mm, 50g) for easy mounting.
  • Strong anti-interference design ensures stable readings in electrically noisy environments.

Applications

  • Outdoor robotics and autonomous vehicle obstacle avoidance in rainy or wet conditions.
  • Industrial liquid level monitoring in tanks or sumps where the probe must be submerged or exposed to moisture.
  • Security and intrusion detection systems for perimeter monitoring in harsh weather environments.
  • Traffic control and vehicle detection systems requiring reliable sensing despite road spray or dirt.
  • Agricultural automation for measuring bin levels or guiding equipment in dusty, humid settings.

Frequently Asked Questions

What is the operating voltage and current requirement for the JSN-SR04T-2.0 sensor?

The sensor operates at a standard 5V DC supply voltage. During active ranging, it draws an average current of approximately 30 mA, with a quiescent current of around 5 mA. Ensure your power source can provide stable 5V power for accurate measurements.

How do I interface the sensor with an Arduino or microcontroller?

Interface is via a simple two-wire digital pulse protocol. Connect the TRIG pin to a digital output on your MCU. Send a 10µs high pulse to initiate a measurement. The ECHO pin will output a high-level pulse; its duration (in microseconds) corresponds to the distance. Use the formula: Distance (cm) = (Pulse Width (µs) * 0.0343) / 2.

Can the sensing probe be used fully submerged in water?

Yes, the separate ultrasonic transducer probe is sealed and waterproof, designed for use in wet, harsh conditions. It can withstand exposure to moisture, rain, and can be partially or fully submerged, making it ideal for liquid level sensing. Ensure the control board itself remains dry and protected.

What is the minimum and maximum reliable detection distance?

The sensor has a specified operational range from 25 cm to 450 cm (4.5 meters). Objects closer than 25 cm may not be detected reliably due to the sensor's blanking time. The maximum range of 450 cm is achievable under ideal conditions with good sound-reflective targets.

What is included in the package and how long is the probe cable?

The package includes the main control board, the waterproof ultrasonic transducer probe, and the connecting cable. The integrated cable between the probe and control board is 2.5 meters long, providing significant flexibility for remote placement of the sensing element.
