Description: 1. A 9V Small Piezo Buzzer is a compact, self-oscillating transducer that converts electrical energy into mechanical vibrations producing an audible alerting sound. 2. Power Consumption: It operates on a wide range of input voltage from 5V to 12V DC, with the preferred operating voltage being 9V for optimal performance and efficiency. 3. Size & Weight: Measuring approximately 20mm in diameter and weighing only a few grams, this buzzer is well-suited for space-constrained IoT projects and portable applications. 4. Versatility: Widely used as alert indicators in various systems such as security alarms, smoke detectors, appliances, and industrial machinery. Also, popular in hobbyist projects like DIY electronic devices, robotics, and educational kits. 5. Sound Output: Produces a loud, clear sound with a frequency range of approximately 1.8kHz to 3kHz, allowing it to effectively capture users' attention even in noisy environments. 6. Electrical Connection: The buzzer can be wired dir
