Description :

- This is a non-contact ultrasonic ranging sensor of high-performance from URM09 series, employing standard PH2.0-3P Gravity vertical interface. - It provides an accuracy of 1% within an effective measuring range of 2~500cm(tested on a flat wall). - Similar to SR04 ultrasonic ranging modules in principle and using method, the ranging function of this sensor is triggered by high/low-level output from the I/O ports of a host, and then the sensor converts ultrasonic flight time into a high pulse to output. - The difference is that this sensor multiplexes input and output signals onto one signal port, which allows users to easily use the sensor for distance measurement only by one I/O port of a controller. - The adoption of advanced hardware and software design ensures excellent and reliable measuring performance. The module works well with 3.3V/5V controllers like Arduino, Raspberry Pi, etc.
