The HC-SR04 is an inexpensive ultrasonic distance sensor that works with Arduino.
Check out the HC-SR04 Holder
- Power supply : 5V DC
- Quiescent current : 15 mA
- Effectual angle: 15°
- Ranging distance : 2cm – 4 m
- Resolution : 3 mm
- Works with Arduino, 8051, AVR, Raspbarry Pi.
There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project!
