Description:

SIM808 module is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation. 
It features ultra-low power consumption in sleep mode and integrated with charging circuit for Li-Ion batteries, that make it get a super long standby time and convenient for projects that use rechargeable Li-Ion battery. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels. Besides, it also supports A-GPS that available for indoor localization. 
The module is controlled by AT command via UART and supports 3.3V and 5V logical level. 

Provide program:                                                                     

• Send a text message in Chinese.
• Send a text message in English.
• Specified calls, automatically hang up after 1 minute.
• Seceived a specified text messages, control LED open circuit.
• Detection module registered to the network, send the message until read a SIM card.       
• Connect to the specified server and send the specified data  by GPRS.                                         
• Provide information of dormant power consumption at about 10 MA.
