HC-SR04P 3-5.5VDC Wide Voltage Range Ultrasonic Proximity Sensor
The HC-SR04 Ultrasonic Sensor is a very affordable proximity/distance sensor that has been used mainly for object avoidance in various robotics projects. It has also been used in turret applications, water level sensing, and even in parking sensors. It is not only capable of running on a wider voltage range coming from the MCU but also it delivers higher accuracy readings, compared to its older version at the cost of losing a tiny bit of the measuring range.
The driving voltage can be as low as 3v to accommodate all the various types of micro controllers (5V max).
The HC-SR04 pin-outs and code are fully compatible with the old version HC-SR04. Users can be seamlessly switched with the old version HC-SR04 if wanted.
