Inside the module, it will send 8 pro 40kHz round electric level with testing the returning wave. Once tested that there is returning wave signal, then it will output echo signal. The pulse width of the echo signal is in direct proportion to the testing distance. Therefore, the distance can be caculated according the duration from the sending signal to receiving signal.

$3.20 Shipping Condition: New Location: China Electret Microphone Amplifier- MAX4466 with Adjustable Gain Maxim MAX4466 20-20KHz Electret Microphone Hover To Enlarge. Description: Add an ear to your ... moreproject with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification. We use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried! This breakout is best used for projects such as voice changers. Audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp(for normal speaking volume about 6" away) which is good for attaching to something that expects'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! Using it is simple: connect GND to ground. VCC to 2.4-5VDC. For the best performance, use the"quietest" supply available(on an Arduino, this would be the 3.3V supply) The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts(it is DC coupled) If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin. You don&#

AS ALWAYS, We strive to OFFER our customers THE BEST integrated solutionS and BEST-IN-CLASS service. Ultrasonic Module HC-SR04. 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.

$3.99 Shipping Condition: New Location: Derry, United States Electret Microphone Amplifier- MAX4466 with Adjustable Gain Maxim MAX4466 20-20KHz Electret Microphone Hover To Enlarge. Description: Add an ear to your ... moreproject with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification. We use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried! This breakout is best used for projects such as voice changers. Audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp(for normal speaking volume about 6" away) which is good for attaching to something that expects'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! Using it is simple: connect GND to ground. VCC to 2.4-5VDC. For the best performance, use the"quietest" supply available(on an Arduino, this would be the 3.3V supply) The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts(it is DC coupled) If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin. You don&#

High level 5V, low level 0V. 4.Sensor angle: Not more than 15 degrees. 5.Detection distance: 2cm-450cm. 6.High precision: Up to 0.3cm 7.Input trigger signal: 10us TTL impulse 8.Echo signal: output TTL PWL signal Mode of connection: 1.VCC 2.trig(T) 3.echo(R) 4.GND. Use method: Product feature HC-SR04 ultrasonic module can offer non-contact distance sensing function. The range of which is 2cm—400cm. and the range accuracy is up to 2mm; the module includes ultrasonic transmitter, receiver and control circuit. The basic operation principle is below: use IO port TRIG to trigger ranging. It needs 10 us high level signal at least• Module can send 8 pro 40 kz square wave automatically. And will test if there is any signal returned. If there is signal returned. Output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic. Testing distance =duration of high level*sound velocity(340m/s) 2. Physical map Refer to the wiring diagram below. VCC supply 5V. And GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.

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.
