op-amps development
Budget: €25 – €65 EUR
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. (https://www.mouser.es/)
