Review Gateway Concentrator RAK833 SPI/USB mPCIe (Multichannel) LoRaWAN # 2

In previous tutorials we have already determined some factors to choose the appropriate (gateway LoRaWAN) for your LoRaWAN application, there are many hardware solutions available, but I have chosen the RAK833-SPI / USB from RAKwireless, a LoRaWAN hub module that It allows to create a multichannel gateway, I consider it the cost-effective option in relation…

Introduction to Lora Server Platform IoT LoRaWAN

Loraserver is a project started in 2015, it is an open source LoRaWAN server, the project provides the components to create LPWAN networks based on LoRaWAN, it includes a user-friendly web interface and the gRPC and REST APIs, each component or module is configurable and they also allow exchange according to the needs of their…

Meter PZEM-004 + Arduino Nano Modbus RTU (RS232) & Platform IoT Node-RED

Originally this test is performed in June 2018 in less than one year, for reasons of availability do not publish, technically just missing the documentation, then I will present the results, well they say there is better late than never. In this opportunity our PZEM-004 meter or it is also possible with our PZEM-004T communication…

Initial Review Meter PZEM-016 Modbus RTU RS485 by PeaceFair

In previous tutorials, we conducted tests with the PZEM-004 y PZEM-004T with display, single-phase power consumption meters , which have great potential for basic applications of electrical consumption measurement or active power. For some months I have a new Peacefair PZEM-016 meter which has features and additional improvements which we will see in the following…

Measurement Electrical consumption with Ubidots Industrial & ESP32 + PZEM-004T

On this occasion I have proposed to measure the electricity consumption of my entire house to make comparative estimates with the collection of my energy bill and analyze. On this occasion I will use the IoT platform Ubidots in its Industrial version, previously we had done tests with the educational version, but this industrial version has special…

10 Professional PCBs for $ 2 with JLCPCB – Ard-LoRa Prototypes

In my last tests I have used platforms like ESP8266 implementing LoRa modulation and in some applications with LoRaWAN, in this opportunity I will use the Arduino platform and I will manufacture a prototype I have contacted again to JLCPCB that they offer a PCB manufacturing service at a very reasonable price. In this opportunity I will use…

Gateway LoRaWan ESP8266 & RFM95 (ESP-LoRa) 915mHz single channel with The Things Network

For a few weeks I have tested with LoRa technology, we have also heard about LoRaWAN, some time later we created an account on the TTN Platform or “The Things Network”, applied especially to these LP-WAN networks, for this new tutorial we will create a gateway LoRaWAN using an ESP8266 module and a Radio Modem RFM95/95W at…

Meter PZEM-004T with Arduino ESP32 ESP8266 Python & Raspberry Pi

In this opportunity we will collect tests with my new electric consumption meter PZEM-004T, making integrations with some of the most known hardware platforms ESP8266, Arduino Nano, ESP32, Arduino UNO + Shield Ethernet W5100 and Python in Raspberry Pi. For a long time I wanted to try the PZEM-004T of Peacefair, I bought my meter…
