Vibration sensor module alarm The motion sensor module vibration switch SW-420 module is based on the vibration sensor SW-420 and comparator LM393 to detect if there is any vibration that is beyond the threshold. The threshold can be adjusted using an onboard potentiometer. When there is no vibration, this module outputs logic LOW, the signal indicates LED light, and vice versa.
If the module does not vibrate, the vibration switch is in the closed state, the output is low, and the green indicator light is on. The product vibrates, the vibration switches momentary disconnect, the output is driven high, and the green light does not shine.
The output can connect to the microcontroller, which detects high and low levels so as to detect whether the environment has vibration and play a role in the alarm.
Note:
Do not reverse the power directions; otherwise, it is possible to burn the chip.
The signal LED light output is low; the signal LED OFF output is high.
The output level is close to the input voltage.
Features:
1. Using the SW-420 normally closed type vibration sensor.
2. Comparator output, clean signal, good waveform, strong driving ability, >15m A.
3. Using a wide voltage LM393 comparator.
4. With bolt holes for easy installation.
Package Includes:
1 x Vibration sensor module alarm motion sensor module vibration switch SW-420.
