AJ-SR04M Waterproof Ultrasonic Ranging Module
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.
