DollaTek 5Pcs SW-420 NC Type Vibration Sensor Module Vibration Switch
Description:If the module does not vibrate- the vibration switch was closed on state- output of low output- the green indicator light.The product vibrates- vibration switch momentary disconnect- output is driven high- the green light does not shine.The output can be directly connected with the microcontroller- which to detect high and low level- so as to detect whether the environment exist vibration- play a role in the alarm.Feature:Using SW-420 normally closed type vibration sensorComparator output- clean signal- good waveform- strong driving ability- >15mAWorking voltage 3.3V ~ 5VOutput format: digital switching output (0 and 1)Using a wide voltage LM393 comparatorWith bolt holes for easy installationSmall PCB size: 3.2 x 1.4cmNote:Power direction cannot be reversed- otherwise it is possible to burn the chipSignal LED light is output Low- signal LED OFF output is HighThe output level close to the input voltageApplication:Various vibrations trigger: Smart car- Earthquake alarm- Motorcycle Alarm- Theft alarmPackage included:5x DollaTek Vibration sensor module
