Whether you are going to go for monitoring any liquid, the sensor is a mandatory part which is included in all metric devices. This is actually the component which is going to be detecting the level of any chemical and providing you the data. With this in mind, there are quite a few different types of <a href="https://level-sensor.jimdosite.com/level-sensor/" rel="nofollow">Telemetry Chemical Level Sensor</a> and yet these sensors are among the most popular ones.

They are using pretty much the same components as you have but it's so much more fun to setup it yourself and learn something from it. <br />I got your solution working however, unfortunately, it too had problems with the sensitivity. I guess that a electret microphone is not suitable for my project and I need something else? Any suggestions or guides? <br /><br />Thanks!

I have used the sparkfun sound sensor board<br />https://www.sparkfun.com/products/12642, but have found that they are firstly overpriced and difficult to calibrate. By replacing R17 with a trimpot, i came quite close to same calibration for 3 boards hooked up to a Teensy 3.5 Digital Inputs 10,11 and 12. <br /><br />I require a circuit which firstly has an opamp (LM358), bandpass filter 300hz-3Khz and an adjustable trimpot for gain and calibration. Output Digital High/Low signal to the Teensy 3.5 for use with interrupts.<br /><br />I have built the circuit as you have designed and found that it is easy to build and fits the specification above except for the bandpass filter. Would you be so kind as to guide me in the right direction in adding a bandpassfilter?Anonymoushttps://www.blogger.com/profile/01083747607951039458noreply@blogger.comtag:blogger.com,1999:blog-7858033185987617764.post-50950883009866237532016-10-21T23:40:24.389-07:002016-10-21T23:40:24.389-07:00So many inportant information are available here a...So many inportant information are available here also have some interesting things.

In other words, there should be no problem adjusting the potentiometer so it doesn't trigger on regular ambient noise. The question is whether the interesting events you want to alert on are significantly louder to where they would trigger above this threshold. I recommend a quick prototype and test in the target environment.David Houldinghttps://www.blogger.com/profile/09271627771243067144noreply@blogger.comtag:blogger.com,1999:blog-7858033185987617764.post-86286496072835139772016-06-24T09:15:26.993-07:002016-06-24T09:15:26.993-07:00I am looking to use something similar to your desi...I am looking to use something similar to your design in an industrial setting. there will a constant noise level and i am wanting to monitor excessive noise levels e.g a machine takes a knock.
