◆400ML ultrasonic cleaning machine can produce 40KHz ultrasonic power, output power is 30W, can provide strong and gentle cleaning effect without damaging valuables. All surfaces can be cleaned in liquid.
◆The ultrasonic cleaning machine vibrates 40,000 times per second, and the water molecules generate a large number of micron-level bubbles under the action of ultrasonic waves, and the bubbles continue to burst under sound pressure, which produces an impact on the surface of the article to achieve the cleaning effect.
◆Ultrasonic cleaner is cleaned with tap water at room temperature, no hot water is needed. If there is oil stains, it is best to add a few drops of detergent (the cleaning effect is higher than 20%).
◆Made of corrosion-resistant 304 stainless steel water tank and ABS shell, sturdy and durable. The large capacity of the jewelry washing machine is suitable for various items, and can be completely immersed in water without overflow.
◆Ultrasonic cleaning machine 360° three-dimensional cleaning is suitable for cleaning jewelry, rings, bracelets, glasses, waterproof watches, 40DB low volume (automatic shutdown in 5 minutes).

5pcs Ultrasonic Module HC-SR04 MELIFE Distance Sensor with 3pcs Mounting Bracket 2 Wire Set for Mega R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee
Parameter -- New Version Power Supply: 3.3V -- 5V DC.
Operating Principle: Ultrasonic HC-SR04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit..
HC-SR04 ultrasonic sensor module: Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning..
Test Distance Formula: The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse, HC-SR04 test distance following formula -- L = 1/2 x T x C (L is the distance, T is the time between the emission and reception, and C is the sonic speed)..
Package Include: 5 x New Version HC-SR04 Ultrasonic Sensors, 3 x Mounting Bracket with Screws, 10 x Female-Male Dupont Cables, 10 x Female-Female Dupont Cables..
The HC-SR04 ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
HC-SR04 Test Distance : high level time velocity of sound (340M/S) /2.
Equipped with anti-reverse pin socket – making the wiring much tighter and convenient.
Uses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator..
