California Prop 65
For a variety of shock triggering effect , reported stolen alarm, smart car , electronic building blocks and so on.
Please note that this module is triggered when the time will be very short induction into small vibration , enough to drive the relay.
- high sensitivity vibration switch , default by SW-18010P vibration sensors
- the comparator output signal is clean, good waveform , driving ability , more than 15mA
- the working voltage of 3.3V-5V
- the output format : digital switching outputs ( 0 and 1 )
- a fixed bolt holes for easy installation
- small PCB board size : 3.2cm x 1.4cm
- using a wide voltage LM393 comparator
Module wiring instructions :
- VCC: positive power supply
- GND: negative power connection
- DO: digital signal output
- AO: This vibration sensors with this function does not work
Instructions for use:
- the product does not vibrate, vibrate switch was disconnected state, the output -side output high , the green light does not shine.
- the product vibration, vibration switch instantly turns on, output of low output , the green indicator light.
- the output can be directly connected to the microcontroller through the microcontroller to detect high and low , thereby detecting whether the vibration environment , played the role of the police.
