What is GSM

GSM is a widely used mobile phone standard. More than 1 billion people in more than 200 countries and regions are using GSM phones. All users can roam freely between mobile phone operators who have signed a "roaming agreement". The biggest difference between GSM and its previous standards is that its signaling and voice channels are digital, so GSM is regarded as the second generation (2G) mobile phone system. This shows that digital communication has been built into the system from a very early time. GSM is an open standard currently developed by 3GPP.

GSM SMS control series module

GSM series short message alarm controller is mainly composed of special industrial GSM module and a high-performance processor. This module is equipped with 2-16 optional relay control and multi-channel switching value input alarm, which can be connected with various alarm sensors to form a short message alarm system. It can control various switching appliances (water pump, relay, lamp...), And with multi-channel switching value input alarm, it can be connected to various switching value sensors (such as water level sensor, smoke alarm, anti-theft alarm...). Through the SMS service function of GSM network, it can conveniently and quickly realize long-distance (where GSM network covers) data transmission and control of general equipment.

The module uses mobile or linkage SIM card to send SMS to the mobile phone number in the device through the mobile phone to control and set parameters of the device without configuring software.
