JSN-SR04T Waterproof Ultrasonic Distance Sensor Module

Measure distance in a project where the sensor probe may be exposed to moisture. The JSN-SR04T module uses a separate wired ultrasonic probe described as waterproof.

Distance sensing for damp or exposed setups

• ✅ ✅ Place the probe where a board-mounted sensor is impractical — the integrated wired probe separates the sensing face from the circuit board.
• ✅ ✅ Read distance through a controller — trigger and echo connections provide the sensor interface.
• ✅ ✅ Plan around the stated range limits — the listing gives a maximum distance of 4.5m and a 25cm blind zone.

Use the sensor in a compatible measurement or automation prototype, wiring the 5V supply, trigger, echo and ground to your controller as specified. The probe format is useful when the electronics board needs to sit away from the sensing point.

The stated measurement range is not a guarantee across all surfaces or environments. Keep the blind zone in mind and confirm the mounting and wiring requirements before installation.

Specifications: JSN-SR04T; 5V DC; 40kHz; stated maximum range 4.5m; blind zone 25cm; probe described as waterproof; module size 41 × 28.5mm.
