The A01NYUB Waterproof Ultrasonic Sensor is a great tool for measuring distance. It works by measuring the time between sending and receiving an ultrasonic pulse to determine the distance to a target. This sensor offers a longer monitoring distance, a wider detection range, and can penetrate smog and dust. It comes with a removable bell - mouth, and when installed, the effective measuring distance is up to 7.5m. The sensor has a closed probe for the transmitter and receiver, which is waterproof and dustproof. All signal - processing units are integrated inside the module. You can directly get the distance value through the Asynchronous Serial Interface at a 9600bit/s band rate, making it easy to communicate with upper - hosts or other MCUs and shortening your development cycle. You can use it with an Arduino controller for projects like backing car annunciators, obstacle - avoidance robots, and object - approaching detection. Specifications include an operating voltage of 3.3 - 5V, an average current of less than 15mA, a blind zone of 28cm, a detection range of 28 - 750cm for flat objects, UART output, a response time of 100ms, a probe center frequency of 40K ± 1.0KHZ, an operating temperature of - 15 - 60℃, a storage temperature of - 25 - 80℃, a sensing angle of 55º with the bell - mouth and 40º without it, and a waterproof grade of IP67. There's also a product wiki available for more information.



Using the A01NYUB Waterproof Ultrasonic Sensor is quite simple. First, check the operating voltage range (3.3 - 5V) and make sure your power supply meets this requirement. If you want to connect it to an Arduino or a Raspberry Pi, use the Asynchronous Serial Interface at a 9600bit/s band rate. You can use it for projects like setting up a backing car annunciator or an obstacle - avoidance robot. When using, be aware of the blind zone of 28cm, meaning it can't accurately measure distances within this range. Also, note the operating temperature range (- 15 - 60℃) and storage temperature range (- 25 - 80℃). Don't expose it to temperatures outside these ranges. For maintenance, since it's waterproof (IP67 grade), you can clean it with a damp cloth. But avoid using abrasive materials that might damage the sensor. The removable bell - mouth can be taken off for cleaning if needed. Check the product wiki for more in - depth information and troubleshooting tips.
