Condition: 100% Brand New Item Type: Ultrasonic Module Material: Semi-conductor Electric SpecificationUS-015 Ultrasonic Distance Measuring Module Working VoltageDC 5V Working Current2.2mA Working Temperature0~+70℃ Output ModeGPIO Induction Angle<15° Detecting Distance2cm-400cm/0.8-157in Detecting Accuracy0.1cm+1% ResolutionAbove 1mm（up to 0.5mm） Pins: Vcc pin: connect to Vcc power (DC 5V). Trig pin: trig terminal connected to the external circuit. Input a high level above 10uS to the pin to trigger module ranging. Echo pin: the Echo end connected to the external circuit. When the ranging is finished, the pin will output a high level with a width equal to the sum of ultrasonic round-trip time. GND pin: Connect to external circuit ground. 1、The new version of US-015 has far more performance than the old version of HC-SR04，the ranging accuracy is better . 2、The resolution is higher than 1mm, up to 0.5mm, and the ranging accuracy is high. 3、Repeated measurement consistency is better, ranging is stable and reliable. 4、This module can accurately measure distance by using ultrasonic ranging principle. 5、It can realize the non-contact distance measurement function of 2cm~4m / 0.8in-13ft. 1 x Ultrasonic Module
