With the increasing demand for automation and remote operation, controlling electrical devices without the need for physical access has become an important area of development in modern engineering.

SIM800L GSM module library for Linux systems like the Raspberry Pi. This library was also successfully tested with SIM800C and should also support SIM800H. This library provides a driver for SIMCom ...

Thank you for your interest in this project. Unfortunately, this project is no longer maintained as I no longer have a functionning SIM800L module. Additionally, the SIM800L doesn't support current ...

Ever wanted to track your bike, car, or even monitor your loved one's location in real-time? Building your own Arduino GPS tracker gives you complete control over your tracking data without expensive ...

Many times like a multimeter, I expected to have a handy serial terminal nearby such that I will connect those two wires [Tx, Rx] of the probe and will be able to see whether the sensor is really ...

Geofencing is one of the greatest technologies of the 21st century. It has a multitude of applications such as car tracking and parcel location tracking. Here is a more exhaustive list of the ...

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 ...
