In this video vi test three ultrasonic distance sensors. HC-SR04 vs. HC-SR05 (HY-SRF05) vs. US-100 (Y401). We compare the specifications, do a field test and evaluate all over compatibility and easy of use.
We are testing the following boards:
- US-100 ultrasonic distance sensor
- HC-SR05 ultrasonic distance sensor/ HY-SRF05 US-100 ultrasonic distance sensor
- HC-SR04 ultrasonic distance sensor
Based on our use areas we then share which sensor we prefer.

And for us, that is the US-100 ultrasonic distance sensor. While it costs a bit more it is still very cheap. One of the key selling points for us is that it can run on 3.3V and not only 5V. Because of that we use it with all Arduino boards, Raspberry pi, ESP8266 and ESP32.
Additionally, the fact that the board can do the timing for you frees you sketch so that you easily can run apps like Blynk. And it allows you to save GPIO pins, since it can only use RX and TX pins. So you get the results via UART / Serial communication.
And of course, it is a very good bonus that the US-100 has a built in temperature sensor and give you more accurate distance measurements.
