Vibration Sensor Module SW-420
The SW-420 Vibration Sensor Module uses the SW-420 vibration sensor along with an LM393 comparator to detect vibrations that exceed a set threshold. This threshold can be adjusted using the onboard potentiometer.
When no vibration is detected, the sensor remains in a closed state, and the module outputs a LOW signal. In this state, the onboard LED indicator is lit. When vibration is detected, the sensor briefly opens, causing the output to switch to HIGH, and the LED turns off.
The output of the module can be connected to a microcontroller to detect HIGH and LOW signals. This allows the system to determine whether vibration is present in the environment and can be used for alarm or alert applications.
Note:
- Do not reverse the power connections; doing so may damage the chip.
- When the signal LED is ON, the output is LOW. When the signal LED is OFF, the output is HIGH.
- The output level is close to the input voltage.
Features:-
- Uses SW-420 normally-closed type vibration sensor
- Comparator output with clean signal, stable waveform, and strong driving capability (>15mA)
- Based on wide-voltage LM393 comparator
- Includes mounting holes for easy installation
Package Includes:-
1 x Vibration Sensor Module SW-420
Specifications:-
Operating Voltage (VDC) | 3.3 ~ 5 |
Dimensions (mm) (L × W × H) | 40 × 15 × 7 |
Weight (gm) | 3 |
