Gravity: URM09 Ultrasonic Distance Sensor (2～500cm, Trig) Shipping:2-4 Weeks You can chain as manyThis 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
