Product Description

JSN-SR04T Waterproof Ultrasonic Sensor Module

Durable Distance Sensor for Harsh Environments

The JSN-SR04T is a waterproof ultrasonic distance sensor, ideal for applications where exposure to moisture or dust is a concern [citation:1][citation:3]. Its integrated design combines the control board and transducer, simplifying installation [citation:10].

Waterproof Design - Suitable for wet and harsh environments (do not submerge) [citation:5][citation:7]
Long Detection Range - Measures distances from 25cm to 600cm with ±1cm accuracy [citation:1][citation:4][citation:10]
Operating voltage: DC 3.0V to 5.5V (typically 5V) [citation:4][citation:10]
The sensor operates at a frequency of 40kHz [citation:3][citation:5]
This sensor is "waterproof" for environmental sealing, not intended to be fully submerged underwater [citation:5][citation:11]

This sensor can be programmed using the same code as an HC-SR04 [citation:2][citation:9].
Ensure a stable power supply as current draw spikes to 30mA during operation.

Troubleshooting

Inconsistent readings:

  • Check power supply stability.
  • Verify sensor placement and beam path is clear.
  • Test within specified range (25-600cm).

Note: The waterproof rating protects against splashes and humidity, not against full submersion for extended periods
