Cheap LoRa Gateway using Pi & RAK831

RAK831 LoRa Gateway

Lately, I have been working with LoRAWAN and I don’t have Lora gateway around. As you might be knowing LoRAWAN network requires a gateway to push data to the internet. As Lora is not an IP based protocol the gateway helps it in doing so. Basically, multiple LoRAWAN nodes transmit data to the gateway and the gateway transfers the concentrated data to server backend. Server backend which resides in the cloud contains a network server which helps in managing the network and the application server which is responsible for the data and…

Mongoose OS Installation on ESP8266 and GPIO Access

mongoose OS

This video is around ESP8266 module and how to flash mongoose OS to it.It also demonstrates some basic GPIO programming using javascript.Mongoose OS claims as an Operating System for commercial connected products with features like Security, OTA Updates, Remote Management. As Arduino framework is not reliable to run in production environment its a good alternative with  Arduino compatibility layer that allows using existing Arduino drivers for prototyping. It is both C/C++ ready for production and  JavaScript is for fast prototyping on the target hardware. The JS API calls C API.…

IOT: Power outlet controlled from internet using WeMOS

IOT Based Power Outlet

This is a simple project to make IOT enabled power outlet. This video is around WeMOS and demonstrates how to use WeMOS with thingspeak to control some loads in my home. This project lets you control your devices which you need to connect to the output sockets. As an online server, I have used Thinspeak.com but you can use any server but you just need REST API. Check out the video to get started.

Information Display System using WeMOS and MAX7219

MAX2219_Dot matrix

This tutorial is all about making a WiFi-based information display system. This system is built around ESP8266 but not the standalone ESP8266 instead WeMOS is used and programmed using Arduino IDE. So In this video, we will check out how to make an information display system like that using Wemos and MAX7219 based dot matrix display modules. The display system fetches data from the local/online server and displays the received. In this system, u can display any data that you want and that’s up to you however over here I…

Control any load over Internet/ based on Temp. & Humidity | SONOFF TH10

SONOFF TH10

SONOFF TH10 /TH16 is a smart switch version of Sonoff which can monitor and set temperature and humidity through the iOS/Android APP eWeLink. Just as the name indicates, the Sonoff TH device supports two current supply specifications: 10A or 16A. It features presetting the range for temperature or humidity. When the temperature or humidity of the environment falls within the range, it will automatically turn on or off the connected devices. It supports three kinds of temperature and humidity sensors AM2301, DS18B20, DHT11 Source: bit.ly/2lCttDp (ITEAD)

Fetching data from server | Arduino/ESP8266

Arduino on ESP8266

Arduino/ESP8266: Fetching data to Server (LOCAL and Online) using WifiClient on from the ESP8266 module using Arduino IDE. The chip first came to the attention of western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer, AI-Thinker. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. However, at the time there was almost no English-language documentation on the chip and the commands it accepted.The very low price and the fact that there were very few external…
