Gravity: URM09 Ultrasonic Sensor (Trig)

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(test 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. Meanwhile, 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.
