The A01NYUB Waterproof Ultrasonic Distance Sensor offers precise distance measurements by calculating the time taken for an ultrasonic pulse to return to the sensor. As a high-performance waterproof ultrasonic sensor with a range of 28cm to 750cm and an impressive ±1cm accuracy, this distance measurement sensor is ideal for various applications, including object detection, obstacle avoidance, and reliable distance measurement in challenging environments. Designed for robustness, this ultrasonic distance sensor comes with a waterproof and dustproof enclosure (IP67), making it a suitable IP67 sensor for use in harsh conditions. The sensor features a removable bell-mouth, which enhances the sensor's detection range and penetration power, allowing this ultrasonic sensor to work efficiently even in environments with smog or dust. The effective measuring distance of this distance sensor is up to 7.5m when the bell-mouth is installed. Features Detection Range: 28cm to 750cm (flat objects), with a resolution of 1mm Accuracy: ±1cm Waterproof & Dustproof: IP67 grade for reliability in harsh conditions Output: UART for easy communication with microcontrollers (MCUs) Sensing Angle: 55º with bell-mouth, 40º without bell-mouth Response Time: 100ms Operating Voltage: 3.3V to 5V Low Power Consumption: Average current < 15mA Probe Center Frequency: 40K±1.0kHz Applications Obstacle avoidance systems for robots and vehicles Distance measurement for industrial and DIY projects Object approaching detection for safety systems Back-up car annunciators or parking sensors Smart devices for precise range sensing Specifications Detection Range (Flat Object): 28cm to 750cm Accuracy: ±1cm Resolution: 1mm Operating Voltage: 3.3V – 5V Average Current:
