SR04 Ultrasonic Sensor Features The SRF04 ultrasonic distance sensor can be used to measure distance with high accuracy. The basic working principle of this sensor is that it produces a high-level signal and sends it to the obstacle. Then the receiver detects the returned wave. The time between the transmission and reception of the signal allows us to calculate the distance to an object. Note When the Trig pin is set High, the sensor generates and sends ultrasonic sound. At that moment the Ech...
