HC SR04 ULTRASONIC DISTANCE SENSOR FOR ARDUINO AVR PIC HC IN INDIA

ULTRASONIC MODULE HC SR04 DISTANCE MEASURING TRANSDUCER SENSOR FOR ARDUINO AVR PIC (Call me for further discounts through coupons)         Description Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The module includes ultrasonic transmitters, receiver and control circuit. The basic principle of work is as follows: (1) Using IO trigger for at least 10us high level signal,            (2) The Module automatically sends eight 40 kHz and detects whether there is a pulse signal back.           (3) IF the signal is 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) / 2,     Technical Parameters   Operating Voltage 5 V DC Operating Current 15mA Operating Frequency 40Hz Max Range 4m Min Range 2cm MeasuringAngle 15 ° Trigger Input Signal 10uS TTL pulse Echo Output Signal Input TTL lever signal and the range
