Product Description
Active Buzzer Alarm Module
Passive buzzer is characterized by:
1. A passive internal sources without shocks・so if the DC signal can not make it with a tweet. Must 2K ~ 5K square wave to drive it
2. Sound frequency controllable・you can make a "Do Lai Mi Fa Suo La Xi" effect
3. In some special cases・you can reuse a console with LED
Active buzzer is characterized by:(OUR PRODUCT)
1. An active internal buzzer with shock source・so long as a power be called
2. Program easy to control・SCM' high and low level can bring sounds・while passive buzzer can not.
