JSN-SR04T / AJ-SR04M Waterproof Ultrasonic Distance Sensor
The JSN-SR04T is a rugged, waterproof ultrasonic distance sensor designed for harsh environments and outdoor applications. Featuring a sealed probe and a wide measuring range from 25cm to 450cm, it’s perfect for non-contact distance measurement in wet or dusty conditions, such as water level detection, waste bin monitoring, and robotics.
With digital signal processing and reliable performance in challenging settings, this sensor delivers consistent results where standard ultrasonic modules might fail. The included control board handles timing and signal interpretation, allowing for simple integration with microcontrollers like Arduino and ESP32.
Features:
- Waterproof ultrasonic probe (IP66 rated)
- Measuring range: 25cm – 450cm
- Operating voltage: 5V
- Accurate and stable readings
- Ideal for outdoor and wet environment applications
- Compatible with Arduino, ESP32, Raspberry Pi, and more
Note: Avoid immersing the sensor in water — the probe is waterproof, but the control board is not.
