US-015 Ultrasonic Distance Sensor merupakan sensor jarak yang memiliki kemampuan pengukuran lebih baik dibandingkan SR-04 adapun spesifikasinya sebagai berikut:
Operating Voltage DC 5V Working current 2.2mA Operating temperature 0 ~ +70 degrees output method GPIO Induction angle Less than 15 degrees Detection distance 2cm-400cm Detection accuracy 0.3cm + 1 hundred
Pin function: No. 1 Pin: connected to VCC power supply (DC 5V). Pin 2 : Connect the Trig terminal of the external circuit to enter a high level above 10uS to this pin to trigger the module. Pin 3 : Connect to the Echo side of the external circuit. When the distance is over, this pin will output a high level with the level width of the round trip time. No. 4 Pin: Connect the ground of the external circuit
