Description

• Vibration sensor SW-420
• The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA
• The working voltage of 3.3V to 5V
• Output form: digital switch output (0 and 1)
• Has a fixed bolt hole, convenient installation
• Using a wide voltage LM393 comparator
• Small board PCB size: 3.2cm x 1.4cm

Good to know:

1. No vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
2. Detected vibration, output high level, the green light is not lit
3. Output can be directly connected to the microcontroller,  to detect the high and low level, thus to detect whether there is a vibration.
