HC-SR04 ultrasonic distance measuring module

The HCSR04 distance sensor is a device compatible with Arduino, Raspberry Pi and ESP8266-based projects. It works on the principle of emitting ultrasound and measuring the time of its return, allowing an accurate determination of the distance to the obstacle. The measuring range is from 2 cm to 500 cm, with a measuring angle of approximately 15 degrees. The supply voltage is 5V, while the operating frequency of the module reaches 40KHz. The sensor fits for building robots, alarms and many other projects. Specification:
