2pcs JSN-SR04T Waterproof Ultrasonic Sensor: 25cm-4M Distance Measuring Module for Arduino
Special Features
- Sealed Waterproof Design: IP67-rated emitter enclosure for outdoor use in rain/humidity (non-submersible).
- Precision Distance Measurement: 25cm-400cm range with 0.5cm resolution at 40kHz frequency and 70° detection angle.
- Low-Power Operation: 5V DC supply with 5mA static/30mA active current consumption.
- Multi-Mode Configuration: Adjustable parameters for diverse applications: reversing sensors/security systems/industrial control.
- Simplified Interface: Trig (RX)/Echo (TX) pins enable distance calculation: (high-level duration × 340m/s) ÷ 2.
