SW-420 overview
The SW-420 is a Vibration Sensor. Main ratings: Dimensions 40 x 15 x 7 mm(LxWxH).; Weight 3 gm.; Output format digital switching output (0 and 1). This page brings together the SW-420 pinout and key specifications, with the full datasheet PDF to preview below or download.
Vibration sensor module alarm Motion sensor module vibration switch SW-420 module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration beyond the threshold. The threshold can adjust using an onboard potentiometer. When this no vibration, this module output logic LOW the signal indicates LED light, and vice versa.
If the module does not vibrate, the vibration switch was closed on the state, the output of low output, and the green indicator light. The product vibrates, the vibration switches momentary disconnect, the output is driven high, and the green light does not shine. The output can be directly connected to the microcontroller, which detects high and low levels, so as to detect whether the environment exists vibration, play a role in the alarm.
It is useful for a variety of shocks triggering, theft alarms, smart cars, earthquake alarms, and motorcycle alarms. This module when compared with a normally open pneumatic shock sensor module, shock triggered much longer can drive relay module the use of the company’s production of SW-420 normally closed type vibration sensors. comparator output signal clean wave well, driving ability, 15mA rated voltage, and 3.3V-5V output: digital switching output (0 and 1) a bolt-hole for easy installation small Board PCB dimensions: 3.2cm x 1.4cm. using the wide LM393 voltage comparator

SW-420 applications
- Security systems: The SW-420 vibration sensor can be utilized in security systems for detecting unauthorized entry or tampering. When attached to doors, windows, or other access points, the sensor can detect vibrations caused by forced entry attempts, triggering alarms or activating security measures to deter intruders.
- Structural health monitoring: The vibration sensor can be used in structural health monitoring systems to assess the integrity of buildings, bridges, or other structures. By detecting and measuring vibrations, the sensor can identify structural weaknesses, excessive movement, or unusual vibrations that may indicate potential structural damage or fatigue.
- Industrial equipment monitoring: The SW-420 vibration sensor finds application in monitoring and maintaining industrial equipment. It can detect vibrations caused by machinery malfunctions, misalignments, or imbalances. By monitoring these vibrations, the sensor can help identify potential equipment failures or performance issues, enabling proactive maintenance and minimizing downtime.
