HC-SR-04 Ultrasonic Sensor The HC SR04 ultrasonic sensor is used to detect the distance of an object between 2-400cm with an accuracy of up to 3mm. This hc sr04 ultrasonic sensor is based on the SONAR principle and hence its working is not affected by sunlight or other ambient lighting conditions making it ideal for outdoor applications also. The sensor works by transmitting a signal and starting a timer simultaneously, it then stops the timer when the receiver receives the signal after bouncing back from the object. Note: The HC-SR04 has a 5V output (which needs to be reduced to 3.3V to work with the Raspberry Pi). Applications: Used to avoid and detect obstacles with robots like biped robots, obstacle avoider robots, path finding robots, etc. Used to measure the distance within a wide range of 2cm to 400cm Can be used to map the objects surrounding the sensor by rotating it Depth of certain places like wells, pits, etc. can be measured since the waves can penetrate through the water
