Ultrasonic Sensor - HC-SR04

With this ultrasonic sensor you can easily measure a distance.

To use the sensor with Arduino see this page: Ultrasonic Sensor HC-SR04 with Arduino Tutorial

The sensor works standard with the trig/echo, but it is also possible to modify the sensor by soldering 10kΩ resistors on the places M1 (R7) and M2 (R8). This means that the sensor can also be used with I2C, 1-wire or UART. However, we cannot provide support for this.

There are holders/brackets available for this sensor.
