The project's goal is to deploy data transmission technology, which has applications in many industrial settings, military and defence situations, and more. In this case, LoRa technology is used since it provides a greater degree of security. It has been shown that the ability to transport and store sensitive data securely is a vital component of both corporate and military success. Prior to transmission, LoRa technology encrypts data at a higher level. The project's foundation is an onboard computer with several input and output ports. These onboard computers are sometimes referred to as micro controllers. The input and output ports of the controller are interfaced with different input and output modules based on the requirements. Stated differently, all of the project's components communicate with one another via the micro controller. This project is divided into two pieces. Both the sender and the beneficiary. A text message will be transferred from the transmitter part to the receiving section via a laptop. The transmitter section's data is sent via LoRa and is encrypted. The original data is shown on a laptop after the microcontroller decrypts the encrypted data it got from LoRa in the receiver section. As a result, buzzers and LCDs give visual and aural alarms.
