Widely used: Sweepers, DIY robot cars, for raspberry pi project,It can be building a little robot to measure distances in a room under construction.
HC-SR04 Ultrasonic Sensor Module: It measures distance by sending out a sound wave at a specific frequency and receiving back that sound wave to bounce.
Good Accuracy: Power Supply :3V-5.5V DC, Detection angle: 003c15 °, Minimum target distance is 2.0cm from the end of the Voltage transducers. Maximum repeatable target distance is 2CM-150CM for a large unobstructed stationary target.
Easy to install: There are 4 pins out of the module, VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output, So it's a very easy interface for controller to use it ranging.
Note: The module should be inserted in the circuit before been powered to avoid producing high level of Mis-operation.

✿❥SHOCKWAVE THEORY: The shock wave pain treatment instrument is a mechanical pulse pressure transmitted through the medium (air or gas), which generates accurate ballistic shock wave from pneumatic pulse sound wave..
✿❥SHOCKWAVE FUNCTIONS: The shock wave can treat a variety of pain: shoulder pain, calcified fasciitis,radial or ulnar epicondylitis,trochanteric tendinitis,lumbar or caudal pain, patellar tendinitis, tibial stress syndrome, Achilles tendon pain, plantar fasciitis, lipotomy, fat mass removal, ED treatment. Shock waves are aimed at the source of chronic pain. Shock waves can dissolve calcium deposits and lead to better angiogenesis, thereby reducing pain..
✿❥SHOCKWAVE FEATURES: Whole body massage,Physical therapy, Lose weight,Body-shaping,in a word,the shockwave is a new-coming perfect muti-functional beauty machine in one..
✿❥SPECIAL SHOCKWAVE ED THERAPY: ED(Erectile Dysfunction)EDSWT uses pulsed acoustic waves, known in Europe as shockwave therapy, to address the root cause of poor sexual performance for men-poor blood flow. By expanding existing blood vessels in the penis and creating new avenues for more blood to flow into the penis, Smartwave produces healthier, fuller and more sustained erections for men with and without....
