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 . Its integrated design combines the control board and transducer, simplifying installation .
Waterproof Design - Suitable for wet and harsh environments (do not submerge)
Long Detection Range - Measures distances from 25cm to 600cm with ±1cm accuracy
Operating voltage: DC 3.0V to 5.5V (typically 5V)
The sensor operates at a frequency of 40kHz
This sensor is "waterproof" for environmental sealing, not intended to be fully submerged underwater
= Technical Specifications =
| Parameter | Value |
|---|
| Power Supply | DC 3.0V ~ 5.5V |
| Static Current | 5mA |
| Working Current | 30mA |
| Frequency | 40kHz |
| Detection Range | 25cm ~ 600cm |
| Measurement Accuracy | ±1cm |
| Resolution | 0.1cm ~ 1mm |
| Beam Angle | 70° ~ 75° |
= Pin Connections (HC-SR04 Compatible) =
| Pin | Function | Description |
|---|
| VCC | Power | +5V supply |
| Trig | Trigger | 10µs HIGH pulse starts measurement |
| Echo | Echo | Pulse width indicates distance |
| GND | Ground | System ground |
Connect Trig to a digital output pin and Echo to a digital input pin on your controller.
This sensor can be programmed using the same code as an HC-SR04 .
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 |
