Abstract

The line of sight (LOS) microwave communication system, especially those operating at frequencies above 10 GHz, is very susceptible to rain attenuation, particularly in tropical countries such as Indonesia. Therefore, it is essential to calculate rain attenuation estimation values as a basis for consideration in designing a line of sight microwave communication system to get stable communication. In this study, telemetering was designed to measure the rainfall intensity from a rain gauge device through a 433 MHz wireless transceiver. Measurement of rainfall intensity values via an Arduino-controlled rain gauge was transmitted directly to the monitoring room, which then processed to be displayed in graphical form in real time and can also be stored as data loggers. The rainfall telemetering device users can measure rainfall remotely and without having to wait for the rain like the rainfall manual measurement.

We propose telemetering of rainfall measurement results using LoRa technology type F8L10D with an operating frequency of 433 MHz

Summary

Introduction

With the increasing need for communication services, the radio spectrum is demanded to have an enormous bandwidth. The transmission method requires a substantial carrier frequency in the range of more than 10 GHz. Communication systems with very high frequencies are very vulnerable to rain [1]–[3] because it weakens the power received on the receiving side and the communication system's general performance. Raindrops cause scattering and absorption of radio wave energy [4], producing damping called rain attenuation. The amount of rain attenuation depends on the amount of rainfall. The rain attenuation affects the communication system that uses frequencies above 10 GHz [5]–[7]. Rain attenuation can only be determined statistically or in estimated values[8]–[11]
