Ultrasonic distance meter HC-SR05.

The ultrasonic distance sensor HC-SR05 (HY-SRF05) can be used for length measurements with the Arduino or for building robots that detect and avoid obstacles. It is easy to control and therefore suitable for beginners. It is almost identical to its predecessor HC-SR04, but offers an improved resolution of 2 mm and an additional OUT pin.

Recommended waterproof alternative: JSN-SR04T Waterproof Ultrasonic Distance Sensor

Recommended Accessories:

• Dupont Jumper Cable Set 20cm 60 Pieces.
• Logic Level Converter 2-Channel 5V / 3.3V

Features:

• Resolution: 2 mm
• Additional OUT pin compared to the HC-SR04
• Operating mode 1: SRF04 compatible with VCC, Trig, Echo and GND
• Operating mode 2: control via a single control line
• Measurement: Trig high for 10 µs, the duration of the Echo signal is proportional to the distance
