Precision HC SRF05 Ultrasound Sensor (2 to 450cm)

The HC-SRF05 ultrasound distance sensor is the improved version of the HC-SR04 sensor capable of detecting objects and calculating the distance at which it is in a range of 2 cm to 400 cm, its main difference is the stability of measurements A do.

The sensor works by ultrasound and contains all the electronics ordered to make the measurement. Its use is as simple as sending the starting pulse and measuring the width of the return pulse. Of very small size, the HY-SRF05 stands out for its low consumption, great precision and low price.
