DESCRIPTION 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 a relay , some people 's information and relay modules can be connected directly to the actual use of ineffective. FEATURE Using the company's various sensitivity vibration switch , default by SW-18020P vibration sensors . The comparator output signal is clean, good waveform , driving ability , more than 15mA3. The working voltage of 3.3V-5V4. The output format : digital switching outputs ( 0 and 1 )5. A fixed bolt holes for easy installation6. Small PCB board size : 3.2cm x 1.4cm7. Using a wide voltage LM393 comparator. Directions: Product no vibration, vibration switch is disconnected, the output end of the output high level, the green light is not bright; Product vibration, the vibration switch transient conduction, output of low level, the green light is lit; Output can be directly connected to micro-controller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police WHAT'S IN THE PACKAGE 1x SainSmart Vibration Switch Shock Sensor Module Alarm Module 4X Dupont Wires
