## Description

Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This A01NYUB Waterproof Ultrasonic Sensor features farther monitoring distance, wider detection range and a certain penetration power(smog, dust). The product comes with a removable bell-mouth and the effective measuring distance is 7.5m when the bell-mouth installed.

This sensor is provided with Arduino example code via the [manufacturer's product wiki](https://wiki.dfrobot.com/A01NYUB%20Waterproof%20Ultrasonic%20Sensor%20SKU_SEN0313), but we've also got it working on a [Raspberry Pi Pico with MicroPython](https://forum.core-electronics.com.au/t/a01nyub-waterproof-ultrasonic-sensor-micropython/15263/6).

**Connection with [Arduino](https://www.dfrobot.com/category-35.html)**

The ultrasonic sensor adopts closed probe of transmitter & receiver, waterproof and dustproof. All the signal processing units are integrated inside the [module](https://www.dfrobot.com/category-156.html), so users can directly obtain the distance value through Asynchronous Serial Interface. With 9600bit/s band rate, the sensor can easily communicate with upper-host or other MCU, which greatly shortens the developing cycle for users.

**Connection with [Raspberry Pi](https://www.dfrobot.com/category-36.html)**

Use the sensor with Arduino controller to build up your projects, such as backing car annunciator, obstacle avoidance [robot](https://www.dfrobot.com/category-37.html), object approaching detection etc.
