51 vibration gsm positioning alarm design-vibration-GSM-GPS

This design is composed of STC89C52 single-chip circuit + vibration detection circuit + GSM short message upload module + GPS positioning module + power supply circuit.

1. If the vibration sensor detects the vibration, the buzzer will alarm (the alarm sound is 10 seconds, after 10 seconds, the buzzer will stop the alarm, if the vibration is detected again, the alarm will be re-alarmed), and at the same time the GSM message will locate the longitude and latitude of the GPS The information (including Dangerous!) is sent to the mobile phone. Otherwise, the buzzer will not alarm and the SMS will not be sent.
