Works but sensitive to noise
The module functions as described, but I had to add some capacitors to filter out electrical noise in my circuit. Once filtered, readings are consistent.

Perfect for Arduino Projects
This US-100 module works flawlessly with my Arduino Uno. The serial communication is stable, and the range accuracy is impressive for the price. Highly recommended for robotics.

Solid performance
Using this for obstacle avoidance on a small drone. It responds quickly and the angle of detection is narrow enough to be useful without too much noise.

Easy to integrate
As a beginner, I found this module very easy to wire up. The 3.3V and 5V compatibility saved me from needing extra level shifters. Great product!

Good value, clear documentation
The sensor is reliable and the included pinout diagram was very helpful. It took a little time to calibrate the code for my specific voltage, but once set up, it performs well.

Better than HC-SR04
I switched from the HC-SR04 to this US-100 and the difference in stability is noticeable. The temperature compensation feature seems to work well indoors.
Q: Can this module be used directly with a 3.3V microcontroller like ESP32?
A: Yes, the US-100 operates within DC 2.4V to 5.5V, so it is fully compatible with 3.3V systems like the ESP32 without needing a logic level converter.
Q: Does this come with jumper caps for selecting the trigger mode?
A: Yes, the package includes jumper caps that allow you to easily switch between UART mode and IO trigger mode by configuring the pins.
Q: How does temperature affect the reading accuracy?
A: The US-100 has built-in temperature compensation which helps maintain accuracy across varying temperatures, reducing errors common in simpler modules.
Q: Is there any library available for Raspberry Pi?
A: While we do not provide an official library, many open-source Python libraries for ultrasonic sensors on Raspberry Pi support the US-100 via its GPIO or UART interfaces.
Q: What is the maximum update rate for distance measurements?
A: The module can provide updates approximately every 60ms, allowing for a refresh rate of around 15-20 Hz depending on your coding implementation.
