![]() ![]() Besides, there are a set of antenna interface on this module.This SIM800L module has a set of TTL level serial interface, a set of power supply interface.TTL serial interface compatible with 3.3V and 5V Microcontrollers, compatible with arduino.SIM800L V2.0 GSM/GPRS Module have many specs, you can check it below: Specification of SIM800L V2.0 GSM/GPRS Module You can easily turn-on or turn-off many objects in your house, such as lamp, fan, and etc. ![]() It’s about how to control relay using SMS controller. Here is just an example project using SIM800L V.2. There are so many GPRS/GSM modules on the market which need to add 5V regulator and level converter circuit, while SIM800L V.2 GSM/GPRS module already has a built-in regulator circuit and TTL level converter on the board. The advantages of these modules are the VCC and TTL serial levels that have 5V voltage, so you can directly connect it to Arduino or other minimum system with 5V of voltage level. The module works to add both of GSM features (voice call or SMS) and GPRS features. SIMCOM SIM800L V2.0 GSM/GPRS Module is a QUAD BAND GSM/GPRS module which compatible with Arduino. ![]()
