Ultrasonic Sensor Distance Module HC-SR04: IO trigger for at least 10us high level signal

The Module will automatically send eight 40 kHz signals and detect whether or not they are returned with a pulse signal.

The time from sending ultrasonic to returning is the time of high output IO duration if the signal returns at a high level. (high level time velocity of sound (340M/S)/2 is the test distance.

5V DC power supply; Quiescent Current:

The performance of the module is consistent, and it accurately measures distance. Ultrasonic ranging modules SRF05 and SRF02 are interchangeable. This module works in conjunction with the GH-311 anti-theft module.

Questions & Answers

What screw size should I use in the corner holes?

I don't have one at the moment, but they appear to be small metric nuts and bolts. It's possible that it'll be 2 or 3 mm.

Selected User Reviews For 2pcs Ultrasonic Module HC-SR04 Distance Sensor with 2pcs Mounting Bracket for Arduino Uno R3 Mega 2560 Nano Raspberry Pi 3 Smart Robotics Projects

Both work as expected and come in a nice package

5/5

This is a review of the Ultrasonic sensors, which come in a nice package and perform as expected. The package arrived in 4 days from NV to CA, thanks to free standard shipping. Although the packaging on the outside is attractive, the interior is less so. The screws and cables are kept in the same zip lock bag as the ultrasonic modules. Not only are the screws loosely bouncing around with the modules during shipping, but one of them has become stuck between the module's delicate crystal and the mount. One of the module's couple pins is bent, and it's most likely factory bent. Excellent customer service and communication; I never have to wait for them to respond. The performance is similar to that of the other ultrasonic sensors I bought. Both can detect distances between a few centimeters and 180 centimeters (-). 12 cm) consistently, but beyond 180 cm, it's hit-or-miss. The price is neither the highest nor the lowest, but it is reasonable if you are in a hurry.
