HW op-amp circuit
Budget: €15 – €50 EUR
A hardware development is required.
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
Operational Amplifier model: we will define it before start the project.
Battery used: 1x3.7V or 1x9V
Software to use: KiCad. Any other software for simulate it (for example LTspice).
