AJ-SR04M Waterproof Ultrasonic Distance Sensor Module for Arduino ESP32.
The AJ-SR04M Waterproof Ultrasonic Distance Sensor Module is designed for reliable, non-contact distance and level measurement in indoor and outdoor projects. Its waterproof ultrasonic probe makes it suitable for applications where moisture, splashes, or harsh environments may be present.
The module uses ultrasonic waves to detect the distance between the sensor and an object without physical contact. It is suitable for Arduino, ESP32, ESP8266 and other microcontroller-based projects, making it ideal for water tank level monitoring, robotics, obstacle detection, parking assistance, smart agriculture and automation systems.
With a wide operating voltage range, low power consumption and stable distance sensing, the AJ-SR04M is a practical choice for DIY electronics, IoT projects and industrial prototypes.
