WWZMDiB 2 Pcs HC-SR04 Ultrasonic Sensor Module Compatible with for Arduino R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee (2 Pcs HC-SR04 Ultrasonic Sensor)

These ultrasonic sensors are amazing. I am using mine connected to an Arduino Uno to measure distance to water in a bucket. As the water is pumped out the water level lowers to a point set in the Arduino code to activate a LED and display Refill Water Bucket on the LCD display, as well as play a tone. Fast delivery, well packaged.

Work well - within tolerance. No Issues

Nice module. I like the mount for it. It came without the ribbon cables. I have plenty of those anyway.

Muy bueno y preciso lo recomiendo. Lo usé para mi proyecto final

Worked really well for my latest Halloween prop! Takes a bit of tuning on distance and frequency of updates, but otherwise great for any solution that requires a simple distance sensor. Definitely a value for the money!

Very good for wiring easy to use

The products are quality, new, the price is right and the shipping is fast.

I found it to be relatively easy to set up and install. However, I have noticed that the readings can be quite inconsistent and can give off false measurements for anything further than 3 meters. While the sensor works well for shorter distances, it can be unreliable for longer distances. It's important to keep this in mind when using the sensor for projects that require accurate distance measurements. Overall, the HC-SR04 Ultrasonic Sensor Module is a decent product that works well for shorter distances. However, if you need more accuracy over longer distances, it might be worth considering a different sensor. I used it with a NodeMCU Arduino board to detect when my car is in the garage.
