## Description

Ultrasonic Rangefinders are great for detecting objects or measuring distance. They rely on echo-location - the same principle bats use to detect obstacles in their environment. These sensors usually require being manually wired into a circuit, so we made the **PiicoDev® Ultrasonic Rangefinder**: a combination of the ubiquitous RCWL-1601 Ultrasonic Rangefinder attached to a smart, addressable, daisy-chainable PiicoDev module. Use the great [Getting Started Guide](https://core-electronics.com.au/guides/piicodev-ultrasonic-rangefinder-getting-started-guide/) to begin with measuring distance and then remix the code to suit your own project's needs!

**Features**

- Great Range - between 0.02m and 4m. Most effective between 0.1m and 2.4m
- Connect many rangefinders together for more complex projects.
- A great [guide ](https://core-electronics.com.au/guides/piicodev-ultrasonic-rangefinder-getting-started-guide/)to get you started
- PiicoDev connector, compatible with Qwiic and STEMMA QT (3.3V only)
- 2.54mm breakout for breadboarding/prototyping
- Manufactured and [supported](https://core-electronics.com.au/contacts/) in Australia by Core Electronics

**PiicoDev Overview**

[PiicoDev](https://core-electronics.com.au/piicodev.html) is a [![](https://core-electronics.com.au/skin/frontend/white/default/images/ce_original_blue.png)](https://core-electronics.com.au/original) ecosystem designed for rapid prototyping and maker education. The range includes:

- [Starter Kits](https://core-electronics.com.au/piicodev.html#category_1322)
- [Sensors](https://core-electronics.com.au/piicodev.html#category_1380)
- [Outputs](https://core-electronics.com.au/piicodev.html#category_1381)
- [Adaptors & Expansion Boards](https://core-electronics.com.au/piicodev.html#category_1307)
- [Platforms](https://core-electronics.com.au/piicodev.html#category_1310)
- [Cables](https://core-electronics.com.au/piicodev.html#category_1309)
- [Accessories](https://core-electronics.com.au/piicodev.html#category_1323)
 
Here are some of the features we have baked into PiicoDev:

- **Unified MicroPython libraries.** The same MicroPython code examples will work on all supported platforms.
- **Simple-and-expandable connections.** Modules can be connected using a 4-pin connector and daisy-chained to expand projects.
- **Breakout pins.** Every module has a breakout section for optional advanced uses.
- **Consistent size.** We have taken care to ensure modules are consistent sizes so that they easy for 3D printing cases, stacking and experimenting with.
- **Creative freedom.** Simmer all of these features together and you end up with lots of creative freedom while still being a hands-on electronics experience.
 
PiicoDev modules are designed by our team in Newcastle and manufactured in Australia and overseas. They’re made for makers and educators alike — affordable, reliable, and easy to use. [Get in touch](https://core-electronics.com.au/contacts/) if you have any questions.
