Vibration Sensor Module/tilt Switch SW-420 Normally Closed Vibration Sensor Module Alarm Sensor Module

Product Features:
 
 
 
It adopts normally open high-sensitivity vibration switch SW-18010P. The switch is in the open-circuit OFF state when it is stationary. When it is touched by an external force and reaches the corresponding vibration force, or when the moving speed reaches an appropriate eccentric (eccentric) force, the conductive pin will generate instantaneous conduction and become an instantaneous ON state; when the external force disappears , the switch returns to the open circuit OFF state. It can be used for various vibration triggers, burglar alarms, smart cars, electronic building blocks, etc. The sensor is specially equipped with M3 fixed mounting holes, which is convenient to adjust the direction and fix. It uses a wide-voltage LM393 comparator, with clean signal, good waveform, strong driving ability, more than 15mA, and an adjustable precision potentiometer to adjust the sensitivity.
 
 
 
Product parameters:
 
 
 
Working voltage: DC3.3-5V
 
Output form: DO digital switch output, AO analog output invalid
 
 
 
Instructions for use:
When the product does not vibrate, the vibration switch is disconnected, the output terminal outputs a high level, and the green indicator light is off; when the product vibrates, the vibration switch is instantly turned on, the output terminal outputs a low level, and the green indicator light is on; the output terminal can It is directly connected to the single-chip microcomputer, and the high and low levels are detected by the single-chip microcomputer, so as to detect whether there is vibration in the environment, and play an alarm function.
 
 
 
Connect VCC and GND, the module power indicator will be on. Put the module on the table lightly, adjust the blue potentiometer on the board until the switch indicator on the board is on, then adjust the potentiometer slightly to make the switch indicator off, and then tap the table with your hand to make the vibration sensor feel the vibration. The indicator light will turn on again. When the vibration stops, the switch indicator light will also be off. This phenomenon means that the vibration can trigger the module, so that the switch indicator lights up.
 
 
 
Notice:
 
 
 
Correct wiring! Do not reverse the positive and negative connections to burn the board electronics. When the module senses a small vibration, the trigger time will be very short, which is not enough to drive the relay. Some people's data show that it can be directly connected to the relay module, but the actual application effect is not good.
