Distance sensor ultrasound HC-SR04 2 - 400cm

Part.no: 41013207
In stock: 102


Ultrasonic 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

Using IO trigger for at least 10us high level signal

The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back

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 timexvelocity of sound (340M/S) /2

Wire connecting direct as following: 1. 5V Supply

2. Trigger Pulse Input

3. Echo Pulse Output

4. GND

If you are sourcing a ultrasonic ranging module , the HC-SR04 is good choose . Its stable performance and high ranging accuracy make it a popular module in electronic market .

Compared to the Shape IR ranging module , HC-SR04 is more inexpensive than it . But it has the same ranging accuracy and longer ranging distance.

More details:

power supply :5V DC

quiescent current : 2mA

effectual angle: 15 degree

ranging distance : 2cm - 500 cm

resolution : 0.3 cm

There are 4 pins out of the module : VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance, it will take the different duration of high level. So we can calculated the distance easily :

Distance = ((Duration of high level)(Sonic :340m/s))/2
