AJ-SR04M Waterproof Ultrasonic Ranging Module

Overview:
The AJ-SR04 is an integrated waterproof ultrasonic ranging module designed with a combined transmitter and receiver structure. It offers a measurement range of 20 cm to 450 cm and supports Mode 1 compatible with HC-SR04 software. The module features an ultra-low standby current of 10 µA and operates on a wide voltage range of 3–5V. By replacing the probe with a lower-residual ripple version, the maximum detection distance can be extended up to 6–7 meters.

Features of the sensor:

• 3–5V operating voltage
• Waterproof design, suitable for harsh and outdoor environments
• Ultra-low standby current of 10 µA
• 5 output modes available
• 20 cm blind (minimum) detection zone
• Wide measuring range: 20 cm – 450 cm (flat wall measurement)
• High resolution and stable performance
• Operating temperature: -20°C to 80°C

AJ-SR04M Sensor Module Application:

Ideal for distance measurement, obstacle avoidance systems, liquid level detection, smart devices, robotics, and industrial automation projects.
