Introduction

RF remote control is ubiquitous in modern life. Some remote control applications in the

automation field of agriculture, industry and home require working distances of hundreds

of meters or in some cases maximum ranges up to a few km. The project involves design

and development of a remote control device with a range exceeding 1 km.

Aim in this project is to set a long range communication system and make an application

of it, using IoT. Applications can be made with this infrastructure is excessively many.

Methodology

LoRa Technology is used for implementation of this project. The term

"LoRa" (Long Range) refers to the extreme long distance which can

be achieved with very little power using a dedicated physical layer

(PHY) based on CSS modulation. Transmission takes place in the

license-free sub-gig ISM bands.

To achieve a longer range, a Yagi-Uda antenna has been designed and

built. Yagi-Uda antenna is the most commonly used type of antenna

for TV reception over the last few decades, which is famous for its

high gain and directivity.
