MQTT in ESP32 with ESP-IDF – ESP-MQTT & Node-RED
Normally if we look for tests with the ESP32 module and the MQTT protocol, they mainly use Arduino IDE for ESP32, there is no problem, but this time we will use espressif development environment “ESP-IDF” or “Espressif IoT Development Framework” for the ESP32 which has more advantages and features for more robust applications. ESP32 Module…
Quick test Amazon Echo Dot (Alexa): ESP8266 WEMOS – Relay 3v DFRobot – Emulating WeMo Switch
Some time ago I made a review of a smart speaker Echo Dot Amazon, Tutorial: Alexa Amazon Echo Dot First Steps and Configuration, this time adding an ESP8266 module Wemos version and a Gravity Relay module to 3v of the DFRobot Online Store, emulate a Wemo Belkin switch. I’m testing the alexa Skills that are…
Integration PLC Panasonic Device Types – Bulk upload devices with Ubidots
En In this opportunity we will carry out tests with a Programmable Logic Controller, in this case a PLC FP-X C14R compact Panasonic brand, we will control it from the IoT Ubidots platform. On this occasion we use 2 very interesting features of the Ubidots platform. Device Types: Creation of advanced properties for our devices….
Review Module Wemos TTGO ESP32 + OLED V2.0 + DHT11
I present a TTGO ESP32 module, this device has caught my attention since it is very complete, I ordered one to the Banggood.com online store for testing, the interesting thing is the union of the well known ESP32 module, DHT11 Sensor (Temperature / Relative Humidity ), 0.96 inch white OLED display, charging circuit for Lithium…
Complete installation Grafana Dashboard in Raspberry Pi 3 B / B +
About 2 years ago I made the first tests with Grafana using an ESP8266-01 module, Node-RED, Mosquitto (MQTT) and the InfluxDB database, by that time I did very basic tests which document in the following article: Tutorial ESP8266 Node-RED Granafa InfluxDB MQTT, in this opportunity I will try to explore more features since there is…
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…
Testing Module ASC201-V1.0 Gosling Converter 0-10V to 4-20mA from ICStation
At an industrial level there is a great variety of control signals in this case we will carry out tests with one of the most used control and monitoring signals in the industrial 4 to 20mA. For this first review we will use a PLC Panasonic but in upcoming tests we will test with other…
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…
