AJ-SR04M Waterproof Ultrasonic Module- Overview
The AJ-SR04M is a waterproof ultrasonic distance measurement module designed for non-contact detection between flat surfaces. Operating from 3 V to 5.5 V, it delivers reliable readings from 20 cm up to 800 cm, with enhanced precision in the 20 cm–250 cm range. Ideal for applications requiring splash-proof sensing, this module pairs with a compatible waterproof probe (sold separately).
Key Features of AJ-SR04M Waterproof Ultrasonic Module-
- Wide operating voltage: 3 V–5.5 V for use with 3.3 V or 5 V controllers
- Detection range from 20 cm to 800 cm for short- and long-distance measurements
- High precision between 20 cm and 250 cm for accurate level and proximity sensing
- Low current consumption: maximum 49 mA at 5 V
- Designed for use with a separate waterproof strip line probe (probe not included)
- Genuine AJ-SR04M module with fast shipping across India from Zbotic
Applications and Use Cases
- Water tank and reservoir level monitoring in indoor and outdoor setups
- Obstacle detection for robotics operating in damp environments
- Automated irrigation systems measuring soil or water levels
- Marine and boat deck distance sensing under splash-prone conditions
- Rainwater harvesting systems tracking cistern fill levels
How to Use AJ-SR04M Waterproof Ultrasonic Module-
Begin by connecting the module’s VCC to 5 V (or 3.3 V), GND to ground, and the Trigger/Echo pins to your microcontroller’s digital I/O. Attach the compatible waterproof probe, mount it facing the target surface, then send a 10 µs trigger pulse. Measure the echo pulse width to calculate distance. Implement basic filtering or averaging in firmware for stable readings in outdoor conditions.

Frequently Asked Questions
Does the AJ-SR04M module include the waterproof probe?
No, the AJ-SR04M module is sold without the probe. You will need to purchase the compatible waterproof strip line probe separately to complete your distance measurement setup.
What trigger signal does this module require?
The module requires a 10 µs HIGH pulse on the Trigger pin. After sending this pulse, the Echo pin outputs a pulse whose width corresponds to the round-trip time of the ultrasonic wave.
Can I use this module in outdoor rainy conditions?
Yes. When paired with its waterproof probe, the AJ-SR04M delivers reliable distance readings in damp or wet environments, making it suitable for outdoor level sensing and obstacle detection.
