3V-5.5V HC-SR04P Ultrasonic Ranging Module

Ultrasonic Range finder has been very useful in many electronic project. It is low cost and teaches us the propagation of sound wave, learning about science while completing your project:) While it is popular, HC-SR04 ultrasonic sensor is 5V operated, so it is difficult to be used with 3.3V system like NodeMCU, Wemos, Raspberry pi, micro:bit or 3.3V Arduino board. No more waiting, we bring you the 3.0V to 5.5V Ultrasonic Ranging Module.

Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with our desires, we'll just have to make do with these handy 3V Ultrasonic Sonar Distance Sensor and a pair of flippers. These ubiquitous sensors are really common in robotics projects, but they can also be used for automation, interactive art and motion sensing. They work at about 2cm to 450cm(5V) or 400cm(3V) away, but we think 10cm-250cm will get you the best results.

These sensors are fast, fairly easy to use, and low cost. Unlike the more common HC-SR04 series, this model can be powered by 3V or 5V and the logic level will be the same. This makes this model great for use with just about any microcontroller or microcomputer. And, its HC-SR04 software compatible so just plug it in and it works the same! (Note the size is different from the HC-SR04 so you may need to make mounting adjustments)

Of course you can also use with 5V system such as Arduino UNO, Arduino Mini and Maker UNO.
