5Pack 3V 80dB Passive Electronic Electromagnetic Buzzer for Arduino Projects with Clear Beep Alerts

Passive electromagnetic buzzer pack 80 dB 3 V 5 pieces Compact passive buzzers designed for clear beep tone alerts in electronic projects and devices. Each unit is an electromagnetic passive transducer rated to produce about 80 dB sound level when driven at 3 V. Sold as a set of five for easy replacement or multiple installations. Key benefits Reliable audible alerts: 80 dB output provides a noticeable beep suitable for alarms, timers, and status indicators. Flexible tone control: Passive design requires an external drive signal, allowing you to generate single tones, melodies, or patterns using a microcontroller or waveform source. Easy system integration: Simple twowire connection works with common drive circuits and PWM outputs from microcontrollers and single board computers. Cost effective pack: Five identical units reduce stocking needs for prototypes, repairs, or small production runs. Electromagnetic operation: Mechanical electromagnetic construction delivers consistent, clear beep tones across units. Important attributes Function: Passive electronic buzzer that produces beep tones when driven by an external AC or pulsed DC signal. Sound level: Approximately 80 dB at rated drive conditions. Operating voltage: 3 V nominal drive. Quantity: Pack of 5 pieces. Compatibility: Suitable for use with microcontrollers, single board computers, alarm modules, timers, doorbells, toys, and other circuits that provide a driven waveform. How it solves common problems Need for alerts: Because the buzzer is passive, you control tone frequency and duration in software or by the driving circuit, enabling tailored alerts for different events. Multiple installations or replacements: The fivepiece pack lets you outfit multiple devices or keep spares on hand, avoiding downtime. Simple wiring and low voltage operation: Works with common lowvoltage control electronics without complex interfacing. Typical use scenarios DIY electronics and prototyping: Connect to a microcontroller PWM output to create audible feedback, status beeps, or simple melodies in prototypes and learning projects. Alarm and notification systems: Install in security panels, smoke or intrusion alarm modules, or industrial warning circuits to provide a clear audible alert when a fault or event occurs. Consumer devices and timers: Use in kitchen timers, toys, measurement instruments, or appliance panels to signal completed cycles or user input. Installation tips Provide a pulsed drive or square wave to produce sound. Continuous DC will not generate a tone. Match drive voltage to the rated 3 V nominal condition for expected sound level. Observe polarity if present in your wiring, and secure mounting to prevent vibration damping that could reduce volume. What you get Five passive electromagnetic buzzers rated for 3 V operation and approximately 80 dB output, ready for integration into electronic circuits and alerting applications. This product is intended for use in electronic projects and devices where a driven audible alarm or notification is required.
