Specification Brand : Respicefinem BulletPoint1 : Frequency Control for Melodic Capabilities: Unlike traditional passive buzzers, this buzzers module enables frequency manipulation, allowing users to create sequences akin to musical notes (''do re mi fa so la si do''), adding an innovative touch to audio alerts in projects BulletPoint2 : Square Compatibility for Dynamic Sounds: Designed to operate with a square input between 2KHz to 5KHz, these piezo buzzer transform DC signals into audible alerts, providing flexibility in creating distinct alert patterns suitable for various notification requirements BulletPoint3 : Multipurpose Control Port for LED Integration:This piezo buzzer has unique application scenarios where control ports can be shared with LEDs to facilitate simultaneous audio and video feedback, enhance user interaction, and optimize component usage in space-constrained designs BulletPoint4 : Convenient Mounting with Fixture Nuts: Equipped with fixture nuts, these buzzer alarm modules ensure easy and secure installation onto any project board or housing, simplifying integration into existing systems without additional mounting hardware BulletPoint5 : Efficient 3-Pin Control for Microcontroller Compatibility: The electric buzzers, driven by a 9012 transistor, features a straightforward 3-pin interface (VCC, GND, I/O) compatible with microcontrollers, facilitating seamless integration into a wide range of circuits operating within 3.3V to 5V range Color : #053 IncludedComponents : No ItemName : Respicefinem 5 Pieces Passive Buzzer Module Low Level Trigger Sound Buzzer Alarm Module 3.3-5v 3 Pin Control Sensor Blocks ItemPackageDimensions_Height : 5 centimeters ItemPackageDimensions_Length : 15 centimeters ItemPackageDimensions_Width : 10 centimeters ItemTypeKeyword : sensor-blocks Manufacturer : Respicefinem Material : PCB, electronic ModelName : Respicefinempz67g8g4h5 ModelNumber : Respicefinempz67g8g4h5 NumberOfItems : 1 NumberOfLithiumMetalCells : 1 PartNumber : Respicefinempz67g8g4h5 ProductDescription : This pack of 5 passive buzzer modules offers a versatile solution for generating customizable sound alerts in electronic projects. With frequency control, square compatibility, multipurpose control options, easy mounting, and efficient microcontroller interfacing, they enhance auditory feedback in DIY electronics, robotics, security systems, and educational projects alike.
Features: Passive buzzer without oscillating source inside, so if you use DC signal, you can't make it scream. It must be driven by a square of 2K~5K. The sound frequency is controllable, and the effect of ''do re mi fa so la si do'' can be made. In some special cases, a control port can be multiplexed with the LED. Equipped with fixture nuts for convenient mounting. The module is driven by 9012 transistor.Uses 3 pin control port.
