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 ...

This project demonstrates how to find an approximate location using a SIM800L GSM/GPRS module and online GSM tower databases. The SIM800L module connects to the GSM network and provides information ...

If you are looking for a compact GSM/GPRS module, you can get the SIM800L from most eBay traders. It is not the most judicious choice, but you can build your own basic GSM projects with a cheap modem ...

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 ...

This simple GSM security switch project is based on Arduino Nano microcontroller (MCU) and SIM800L GSM modem (Fig. 1). The cellular-based alert system is configured to send an SMS in response to a ...

LilyGo has launched several TTGO boards usually based on Espressif ESP8266 or ESP32 over the years. Here’s another that could be useful if 2G cellular networks have not sunset in your country: TTGO ...

I've got a couple of SIM800L modules in remote devices that have been running for years. A few days ago both stopped registering with the (One NZ) network at the same time, and no longer connect at ...

This project aims to replace a SIM800 module with a BK A7670E (4G) module without modifying the original hardware configuration, if the size allows it The goal is to allow an update of the system ...
