Gravity: URM09 Ultrasonic Distance Sensor (2～500cm, Trig) Shipping:2-4 Weeks 1″ pin spacing allows compatibility

1″ pin spacing allows compatibility with standard perfboards

Input voltage: 2 V to 16 V (note: this regulator requires 3 V to start

More efficiency means less energy is wasted in the form of heat

it means you can connect this device to any DCE (Data Communication Equipment) such as Modems or any DCE device equipped with a female DB9 connector

You can chain as many as you'd like although after 5 or more shields you may run low on RAM if you're using an UNO

Gravity: URM09 Ultrasonic Distance Sensor (2～500cm, Trig) Shipping:2-4 Weeks 1″ pin spacing allows compatibilityThis 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
