HC-SR04 Ultrasonic Sensor
- HC-SR04 Ultrasonic Sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it is possible to calculate the distance between the sonar sensor and the object.
Technical Specification
- Power Supply :+5V DC
- Quiescent Current : 3mA
- Working Current: < 5mA
- Effectual Angle: <15°
- Ranging Distance : 2cm - 450 cm
- Resolution : 0.3 cm
- Measuring Angle: 30 degree
- Note: The module should be inserted Fortunately, the circuit board re-energized, and avoid the high malfunction, if they have re-energized before they solve.
HC-SR04 Themodule works
- IO trigger ranging to at least 10us high signal;
- Module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
- The signal to return, a high IO output, high duration of
- Test distance = ((Duration of high level)*(Sonic :340m/s))/2

Ordered a ton of these to build an acoustic levitator for my physics class the transducers work well though I will say the polarity of the transducers are not consistent which has led to some slight issues due to one of the tines being connected to the housing which closes the circuit if that time happens to be opposite of its neighbors and the housings touch. Other then that small inconvenience these have all been pretty solid transducers for a good price
