Description:
This is SW-420 NC Type Vibration Sensor Module Vibration Switch for Arduino Smart Car. When the module is not vibrating, the vibration switch has been set to low output state output, the green indicator light is closed. The product vibrates, vibration switches momentary disconnect, output high drove, the green light does not light up. The output can be connected directly to the microcontroller, which detects the high and low levels, so as to detect whether the environment emitted the vibration, play a role in the alarm.
Features:
- Use SW-420 normally closed vibration sensor
- comparator output, clean signal, good waveform, strong driving ability, 15mA
- Operating voltage 3.3V ~ 5V
- Output format: Digital switching output (0 and 1)
- With a wide voltage LM393 comparator
- With screw holes for easy installation
Caution:
- The current direction cannot be reversed, otherwise, it is possible to burn the chip
- Signal LED light output low, signal LED OFF output is high
- The output level close to the input voltage
Applications:
- Various oscillations trigger
- Arduino projects
- Earthquake alarm
- Motorcycle alarm
- Anti-theft alarm
Package Included:
1 x SW-420 NC Type Vibration Sensor Module Vibration Switch
