Lora

Vamos praticar como usar o escudo LORA com arduino UNO. Você precisará de dois Arduinos e dois Shield LORA do Kit do DRAGINO, não se esqueça do cabo USB. LoRa Shield permite que o usuário envie dados e alcance alcances extremamente longos com baixas taxas de dados. Ele fornece comunicação…

Technology Solution Owl deploys a cost-effective, customizable, and easy-to-use IoT device called a Ducklink or “Duck”. A cluster of these ducks generates a resilient communications and sensor mesh network called a ClusterDuck Network (CDN). A CDN can be deployed on ground, on water, in air, and even in space. Once a network…

The Utopia for distributed hardware protagonists are reward models that simply converted client billing in to rewards. The reality is that building a client base from scratch with sufficient purchasing volume so as to enable hardware host rewards at a level that retains engagement is incredibly time consuming, it is…

At Paluni we get asked a lot why we are focusing on 4G/LTE as opposed to 5G when other network providers are doing the opposite. The answer to this question comes in two parts: Firstly, we focus on 4G/LTE because our core network business is to deliver connectivity to areas…

Este artigo mostra como utilizar muitos módulos de Wireless no mesmo nó sensor e alternar entre eles. Como exemplo, vamos considerar 3 nós sensores. Um transmissor com dois módulos de Wireless(ZigBee e WiFi), e dois receptores tendo cada um deles um módulo de Wireless. O padrão do primeiro é ZigBee…

O objetivo deste artigo é fornecer uma visão geral técnica introdutória para LoRa e LoRaWAN. Redes de longa distância de baixa potência (LPWAN) são projetadas para suportar uma grande parte dos bilhões de dispositivos previstos para a Internet de Coisas (IoT). O que é LoRa? LoRa (short for long range) é uma técnica de…

Introduction In early December 2021 Panther started taking orders for their new Helium miner, the Panther X2. As well as many others did, I myself ordered a unit. When it arrived, I was quick to set it up, and I found it to be a high performing miner. In early February…

ช่วงก่อนปีใหม่ ผมได้โจทย์ให้เซต ChirpStack LoRa Network Server เพื่อรองรับการใช้งาน LoRa Protocol ซึ่งก็ผ่านไปได้ด้วยดี ที่ ChirpStack Application มีข้อมูลแสดงสำเร็จ ไม่มีปัญหา ปัญหาอยู่ตรงนี้ !! เราต้องเก็บข้อมูลลง AWS S3 ด้วย เนื่องจากโปรเจคนี้เป็นโปรเจคด้าน IoT ที่ Device คือมิเตอร์น้ำ Drago (โดยบริษัท อาซาฮี-ไทย อัลลอย จำกัด) ในปัจจุบัน เราใช้ AWS IoT Core เพื่อ Subscribe รับข้อมูลจาก Drago CONNEX (Data Logger ของระบบ) จากนั้นนำมา Map เป็นไฟล์ JSON หลาย ๆ ไฟล์ ที่แยกเป็นหลายไฟล์เพื่อความสะดวกตอนเรียกใช้งานในมิติต่าง…
