Sonar Ultrasonic Sensor (HC-SR04)
Working Voltage DC 5 VWorking Current 15mAWorking Frequency 40HzMax Range 4mMin Range 2cmMeasuring Angle 15 degreeTrigger Input Signal 10uS TTL pulseUltrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The basic principle of work: (1) Using IO trigger for at least 10us high level signal, (2) The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back. (3) IF the signal back, through high level , time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340M/S) / 2Supplier: FAMOUS ELECTRONICS BD
