The US-015 Ultrasonic Distance – Measurement Module can detect distances ranging from 2cm and up to 4m (700cm stable). It can be used with any microcontroller such as Arduino. It has 4 pins, 2 of which are for 5v power (VCC – GND) and two pins for data. Specifically, it can be used in a great variety of projects like robots or any other automation. Also, it is widely used for education due to the ease of use. It is very similar to HC-SR04 module, it has although some differences in range, resolution and frequency. Specifications Resolution up to 0.5 mm Can realize 2 cm to 4 m non-contact ranging function, the power supply voltage is DC 5 v, working current is 2.2 mA, support GPIO communication mode Operating temperature:0~ 70° Output mode: GPIO Detection angle: less than 15° Detecting precision: 0.1cm 1% Size: 45mm*20mm*1.2mm
