Active Low Level Trigger Buzzer Alarm Module For DIY MCU Scm

A 5V Active Alarm Buzzer Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is a 5V DC Electronic Part Active Buzzer Module. Using top-quality material, it is durable in use. What is more, an active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke. A good choice for you all! Package Includes: • 1 x 5V Active Alarm Buzzer Module for Arduino. • 3 x F-F Jumper cable. Specifications and Features : • Product Name:3.3 to 5V Active Buzzer Alarm Module Sensor And 3 Pin TTL Cable • The Transistor drive module uses 8550 • With fixed bolt hole- easy installation- 2.6mm aperture. • Operating voltage 3.3V-5V Features: Passive buzzer features are: • Passive internal shocks without source- so if you can not make it with a DC signal tweet. Must be a square wave 2K ~ 5K to drive it • Sound frequency control- you can make a “more than a meter hair Suola” effect. • In some special cases- you can reuse a control and LED mouth Active buzzer features are: • An active buzzer with a concussion internal source- so long as it will be called an energized • The program is easy to control- SCM can let a high-low sound- while the passive buzzer did not. Module interface specification (3-wire) • + External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU) • - External GND out external microcontroller IO port
