Safety deposit box text message alarm device based on acceleration sensor

The utility model relates to an antitheft alarm device, in particular to a safety deposit box text message alarm device based on an acceleration sensor, which comprises an MSP430 microprocessor, the acceleration sensor, a temperature sensor, a TC35i module, a voice chip, a microphone, a loudspeaker, a keyboard and an LCD liquid crystal display. The MSP 430 microprocessor is connected with the acceleration sensor, the temperature sensor, the TC35i module, the voice chip, the keyboard and the LCD liquid display respectively, the microphone is connected with the TC35i module and the voice chip respectively, and the TC35i module is connected with the voice chip and the loudspeaker respectively. The safety deposit box text message alarm device has the advantages that firstly, the acceleration sensor detects whether a safety deposit box is shifted or picked, and a GSM module alarm technique combined together is the most important point, secondarily, three different alarm modes including text message, voice and telephone are utilized, and thirdly, the safety deposit box text message alarm device takes low energy consumption into consideration.
