As an engineer, you are supposed to choose the transducer for AUM (American University of the Middle East) The solution must be finished before the end of January 2022 You are supposed to find the best fit for the Piezo sensor device, which will be able to produce a clear sound. The Piezo sensor device will be used for the alarm system so it must have a low power consumption o The Plate size diameter of the transducer should be equal to or between 22 mm to 43 mm o The Resonant frequency range is from 2.2 kHz to 6.5 kHz. o The external height should be less than 0.54 mm. o The strain accuracy should be equal to or less than +16 um. o When buying the transducer, the designer should not pay more than 2.5 £ (GBP) o As per the requirement to produce clear sound, the capacitance should be higher than 22200 pF,

Choose which of the following transducers are suitable for your solution.

Adafruit Optical Fingerprint Sensor Overview Time left 0:31:41 Secure your solution with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are typically used in safes- there's a high-powered DSP chip that does the image rendering, calculation, feature finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. You can also enroll new fingers directly - up to 162 fingerprints can be stored in the onboard FLASH memory We like this particular sensor because not only is it easy to use, but it also comes with fairly straightforward Windows software that makes testing the module simple - you can even enroll using the software and see an image of the fingerprint on your computer screen But, of course, we wouldn't leave you a datasheet and a "good luck!" - we wrote a full Arduino library so that you can get running in under 10 minutes. The library can enroll and search so it's perfect for any solution (adafruit/aRz). We've also written a detailed tutorial on wiring and use (adafru.it/clz). This is by far the best fingerprint sensor you can get Supply voltage: 3.6 - 6.
