The homemade GSM car security system employs a simple yet effective circuit design that integrates a GSM module, microcontroller, and various...
DIY mobile phone jammer Schematic Diagram
A DIY GSM jammer schematic diagram designed to disrupt cellular mobile phone signals operating within the GSM1900 frequency range of 1930 MHz to 1990 MHz. The GSM1900 standard is utilized in the USA, Canada, and most countries in South America....
Wireless Data Communication system
This project is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless. At the receiver end...
GSM Remote Control MotherBoard Schematic
The entire remote control is managed by a PIC that oversees the GSM/GPRS module's operations, monitors room temperature via a Dallas DS1820 smart probe, controls the logical state of two opto-isolated inputs, and sends commands to two relays. Additionally, the...
Mini GSM localizer without GPS
A localizer that does not utilize GPS technology has been developed using the cost-effective SimCom SIM900 module. In previous discussions, the GSM section was presented, and now the complete localization system is introduced. This system allows for object localization without...
