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 ...

This project uses a GPS module and a GSM SIM800L module to obtain location data and send it via SMS to a specific phone number. This code is designed to read location data (latitude and longitude) ...

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 ...

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 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 ...

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 ...
