Sound & Light Vibration Detection Sensor Alarm Module for Arduino
This module is mainly used for beginners to know the vibration sensor application and DIY project. It can also be used as a simple robot vibration detection module. - Application: teaching£¬ training£¬ robotic£¬ DIY. - Power supply: DC 3~5V. - CGQ1 is vibration sensor (vibration switch: SW-180). When vibration occurs£¬ this switch is kept in contact£¬ disconnected. HQS1342 detects this changing signal and it is determined that there is a vibration. W1 is resistance with adjustable sensitivity. Clockwise rotates to increase the sensitivity. SEL is a short jumper block for choosing the alarm time£¬ connects to the 5th pin of HQS1342. When this pin is at low level and a vibration is detected£¬ then the module will intermittently alarm 30 times; When this pin is at high level£¬ the module will intermittently alarm 3 times. SP1 is buzzer£¬ D1 is light-emitting diode£¬ R1 is current-limiting resistance. When a vibration is detected£¬ buzzer SP1 and diode D1 will intermittently give out sound and light alarm. When the 6th pin of HQS1342 outputs high level£¬ the alarm will stop; When the 6th pin outputs low level£¬ this signal can be used to build application circuit with other modules.
