Active Buzzer Alarm Module Sensor Beep Audion Control Panel for Trigger 3.3-5V
Specifications:
Passive buzzer Low level trigger:
There is no vibration and source inside the passive, so if the DC signal cannot make it whistle, it must be driven by a square wave of 2K~5K, the sound frequency can be controlled, and the effect of "Doramifa Solassie" can be achieved. , In some special cases, a control port can be multiplexed with the LED.
1. The module is driven by s8550 triode
2. Working voltage 3.3V-5V
3. With fixing bolt holes for easy installation
4. Small board PCB size: 32mm*13mm
Interface Description:
3-wire system
