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. 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. 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.

MESR-100 V2 ESR/ Low Ohm In Circuit Capacitor Meter(UK STORE) Can Buy It Now in my ebay store" THIS LISITING ITEM LOCATION AT UK STORE. CAN SHIP ... moreTO UK LOCAL OR EUROPE COUNTRIES IMMEDIATELY. Features: JINGYAN MESR-100 V2 Auto-ranging capacitor ESR and Low Ohm Meter Measuring range from 0.001 to 100.0R. Support IN CIRCUIT Testing. Using true 100 KHz sine wave to measure the ESR value. Which is equal to the testing method of capacitor manufacturer. In the market. There is some technique using short pulse method to testing, but the value will be varying vs the capacitance and sometimes reading is different from the manufacturer's value. What is ESR of capacitor? There is a series resistor inside capacitor. Using 100kHz to remove the impedance 1/2*pi*F*C) the impedance become small, and we can then measure the true series resistor value. A bad E-capacitor will have larger ESR and create large ripple rather than filtering noise. Normally. A big capacitor is larger than 3 ohm. Using this theory. We can measure the capacitor is bad/ damaged or good in condition. Because our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor. As a result we can use it as in circuit test. Because this low testing voltage, it cannot turn on the semiconductor inside a circuit under testing. During repairing TV. LCD, Audio board, etc. we can in circuit testing the capacitor is good or not. Dual terminal. For fast and easy inspect general capacitor or resistor, a printed ESR table for fast check Compare MESR100 old V1 and new V2 Improvement: 1) Change square wave to sine wave 100 KHz. Reduce square wave’s high frequency component, and affect the reading passing the test leads and capacitor. 2) Higher Resolution up to 0.001 ohm. 3) 128X64 dot matrix LCD. With more larger value display and information 4) Embedded 25V capacitor table at LCD. Auto display the capacitor is good or bad reference to common 25V electrolytic capacitor. 5) New plastic case. Curve design for hand carrying. New stand for 60 degree stand
