€25-65 EUR

Paid on delivery
Only a hardware development is required. No code. Time for project development: max 6 days. Sensor used for input: piezoelectric Microcontroller used to receive the amplified sound: ESP32. Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V (half of 3.3V) Operational Amplifier model will be defined before start the project. We have some circuits tested but with problems as clipping and sensitivity signal. Signal amplification should be the higer possible. In oder to avoid the noise, a 10-15Hz filter can be used. We can cut any input or output signal above a specific voltage threshold Battery used: 1x3.7V (voltage used as input for sensor = 3.3V) Software to use: KiCad for schematic and any other software for simulate it (for example LTspice). Project files will be provided. Mouser reference will be used for the BOM. ([login to view URL])

Hello, I have decades of experience in electronic circuits design, especially analog ones. Regarding high gain amplifiers, I recently designed a load cell amplifier with the gain order of magnitude that is required for your project. An important aspect for piezoelectric sensors is to ensure a high impedance. I know how to do that. Please DM me to unvail the sensor datasheet so that I may refine my bid. The idea of a LP filter is good. I'm also an expert for filter design. A Sallen & Key cell should do the job well. For the rest, I think I understood well all your requirements. Regards, Jean-Paul

Hello based on experience your clipping signal might be as a result of the type of opamp you're using for amplification as I have experienced it before also I can design a low pass filter to solve this as well as select an appropriate opamp for you to use for your design .l am highly experienced in electronics and embedded systems and I believe I have the solutions to your design issues. More details will be shared when contacted.
