Ultrasonic Distance Sensor HC-SR04 3-5V Version

Add obstacle detection to your robotics, electronics, or Arduino project with the HC-SR04 Ultrasonic Distance Sensor. Designed specifically for 3-5V operating voltages, it is compatible with typical Arduino voltage ranges.

This economical sensor provides non-contact distance measurement from 2cm up to 400cm with a ranging accuracy of 3mm. Each module includes an ultrasonic transmitter, receiver, and control circuit.

The sensor has four pins: VCC (power), GND (ground), Trig (trigger signal), and Echo (echo signal). It is also usable with BBC micro:bit projects if powered by a separate 5V power supply.

Features:

• Add obstacle detection to robotics, electronics, or Arduino projects.
• Compatible with micro:bit when using a separate 5V power supply.
• Non-contact measurement range from 2cm to 400cm.
• Ranging accuracy up to 3mm.
• Includes ultrasonic transmitter, receiver, and control circuit.
• 4 Pin interface: VCC, Trig, Echo, GND.
