Normally Closed Type Vibration Sensor Module Alarm Sensor Module
For a variety of vibration the triggering effect reported theft alarm£¬ smart car£¬ earthquake alarm£¬ motorcycle alarm. Compared with normally open type vibration sensor module£¬ it has longer trigger vibration time£¬ can drive relay module. Module Features: 1£¬ SW-420 using normally closed type vibration sensor. 2£¬ the comparator output£¬ the signal is clean£¬ good waveform£¬ strong driving ability£¬ exceed 15mAh 3£¬ operating voltage 3.3V-5V 4£¬ Output form: Digital switching output (0 and 1) 5£¬ a fixed bolt hole for easy installation 6 small board PCB size: 3.2cm*1.4cm 7£¬ Wide voltage LM393 comparator Instructions: 1£¬ When the product does not vibrate£¬ vibrate switch will be in closed conduction state£¬ the output terminal output low level and the green indicator light will be on; 2£¬ When the product vibrates£¬ vibration switch will instantly disconnect£¬ the output terminal output high level and the green light will not be on; 3£¬ The output terminal can be directly connected to the microcontroller£¬ with the microcontroller to detect high and low level£¬ thereby detecting the vibration environment£¬ play an alarm role.
