SIM800L GSM module library for Linux systems like the Raspberry Pi. This library interfaces the SIM800L GSM device and allows sending, receiving and deleting SMS messages, as well as performing HTTP ...
Linux system with a UART serial port, or Raspberry Pi with Raspberry Pi OS (this library has been tested with Buster and Bullseye). External power supply for the SIM800L (using the Raspberry Pi 5V ...
Because the SIM800L module is very flexible, a great GSM project design can be relatively simple. But there are a number of reasons for experimenting with more complex ideas, such as enhanced ...
It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...
Abstract: The Fingerprint Door Lock (FPDL) using Arduino with SIM800L research is designed to improve the security and convenience of door access control by integrating fingerprint recognition with ...
