SW420 Vibration Sensor

The vibration module based on the SW-420 vibration sensor and the LM393 comparator to detect any type of vibration signal beyond the vibration threshold. The threshold can be adjusted by the potentiometer it has included. When there are no vibration signals, this small module is responsible for making this known through a low and high state LED indicator, as appropriate; It is characterized by having a single digital output signal that can be treated by an external device, such as a microcontroller, so a specific function can be carried out, depending on the user's needs, since this sensor module is usually implemented for theft alarm systems, intelligent vehicles, earthquake detection alarms, Alarm for motorcycles, among others.

MAIN FEATURES:

• Operating voltage: 3.3V-5V.
• Operating Current (LM393): 15mA.
• Potentiometer adjustable sensitivity.
• digital output (DO).
