WYPH Ultrasonic Module HC-SR04 Distance Measuring Ranging Sensor for Arduino UNO for Mega R3 Duemilanove Nano Robot Pack of 10pcs
Product Description
WYPH Ultrasonic Module HC-SR04 Distance Measuring Ranging Sensor for Arduino UNO for Mega R3 Duemilanove Nano Robot Pack of 10pcs
- 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 time velocity of sound (340M/S) /2
- Power supply :5V DC, quiescent current : <2mA,effectualangle: <15 ranging distance : 2cm~500 cm resolution : 0.3 cm
- Package Content: 10pcs HC-SR04
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.Â
The all process is: pull the Trig pin to high level for more than 10us impulse, the module start ranging;Â
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.Â
So we can calculated the distance easily: Distance = ((Duration of high level)*(Sonic :340m/s))/2
