Welcome @JanhaviDeshpande, to the community!

Many details are still missing:

  • buzzer data sheet (link to the data sheet would be fine)
  • what supply voltage will the buzzer have
  • what frequencies should the buzzer emit and at what volume?
  • which waveforms should be sent to the buzzer?
  • are you planning to use an amplifier stage, if so, which one (or do you need proposals)?

Regards
/Peter

First of all, Thankyou Sir for replying to the message.

Basically, using TMB12A05 active buzzer for a project based on anamoly detection based on audio. Basic functioning includes giving alert.

Still not enough information on what you're trying to achieve.

  • "based on audio" - So do you have something that detects this audio? Microphone? Describe what this anomaly consists of.
  • The buzzer has a frequency range of 2300+/-300H. You need to have some kind of driver for it as well, which you haven't provided any schematic.
If smoke escapes your device, put the smoke back in. It'll still work as a conversation piece. If you find my answers useful, click the Accept as Solution button so that way others can see the solution.

What's that?

As @Peter BENSCH said, give a link to its datasheet.
