Testing Industrial Platform Groov and ESP8266 NodeMCU

This time we will test the Groov platform, but what is groov? Is a solution (IIoT) created by Opto22 for the visualization, control and monitoring of industrial equipment from pc, mobile devices, tablets, smartphones and smart tv. It supports SNAP PAC controllers, Modbus TCP / IP devices and other PLC controllers from other brands such…

Tutorial ESP8266 Node-RED Granafa InfluxDB MQTT

Based on the previous instructions of the ESP8266 connection with the Node-RED implementing the mqtt protocol, we have performed tests of the connection of several software platforms for the collection and visualization of data. We consider these 2 Grafana and InfluxDB for development and Interactive From the internet of things. Install Node-RED Installation Node red Platform…

Tutorial Amplifier Audio PAM8302A ESP8266 Node-RED MQTT

There is a great variety of arduino tutorials generating melodies, one of the most common the famous “Imperial March” of the well-known Star Wars movie, I downloaded one of the examples for Arduino I made several modifications to work on an ESP8266 01 and I have included An audio amplifier to this test. We have also…

Tutorial ESP8266 DS18B20 Temperature Node-RED MQTT (Mosquitto) IoT

This time the integration of ESP8266 and the Node-RED platform was realized integrating a sensor DS18B20 of Protocol of Temperature Onewire. From an HMI or SCADA Web creator on Node-Red-Dashboard using the MQTT protocol and the pubsubclient library converting the ESP8266 into the MQTT Client will perform the sensor reading periodically. Video Test ESP8266  Temperature DS18B20…

Tutorial ESP8266 Control Servo Node-RED MQTT (Mosquitto) IoT #2

This time the integration of ESP8266 and the Node-RED platform has been made integrating an actuator in this case a servo controlled by PWM with rotation from 0 to 180 degrees. From an HMI or SCADA Web creator on Node-Red-Dashboard using as base the MQTT Protocol and pubsubclient library converting the ESP8266 into MQTT Client….

Update ESP8266 Industrial Modbus TCP IP V2.0

 There have been numerous applications in the ESP8266, I have taken as a goal to integrate this module into one of the industrial protocols most commonly used Modbus TCP IP, it would be good to have a node or sensor that sends data or a driver, OPC, PAC, PLC, HMI or SCADA. A long time…

Blink ESP8266 03 ESP 03 in Arduino IDE

Testing the ESP8266 03 have noticed differences with ESP version 01. By default brings AT commands, using the example blink and modifying 02 to activate the GPIO output. Connection to Program ESP Should the GPIO 0 to GND to place the bootloader mode module, its programming is equal to ESP 01 only this one does…

New ESP8266 03 ( ESP 03 )

ESP8266 03 I have done extensive testing with ESP8266 01 (ESP 01), I think it has endless applications, but I decided to test another module of the same family, in this case ESP8266 03 (ESP03), say that your great serious advantage has 7 GPIO (I / O). Characteristics  1. Support 802.11 B/G/N 2. Communication range…
