Group of devices and hardware platforms used in PDAControl.
This time the test is performed on the well-known Cayenne platform. What is Cayenne? It is a solution for building IoT applications based on platforms known as Arduino, Raspberry pi, ESP8266 and Serial devices, Wi-Fi, Lora devices, also includes a Mqtt API to connect any MQTT client which to use in this case, in This…
This time the test will be carried out to the aREST.io platform. What is aREST.io? Is a solution for building IoT applications based on platforms known as Arduino, Raspberry pi, ESP8266 and devices, Serial and Wifi in this tutorial will explain the following: 1- Create a Starter account in aREST.io Official page: arest.io This tutorial…
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…
For this test Users of a Panasonic FPX C14R PLC that have communication via serial RS232 and its protocol is Mewtocol, an ESP8266 01 module configured to function as an Ethernet Serial bridge has been integrated, of course adding a MAX232 chip that performs TTL conversion to RS 232. The result of this test is…
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…
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…
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…
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….
To integrate the module ESP8266 with node-red IoT platform has been used MQTT protocol, there are client libraries for esp8266 as MQTT in this case I decided to use the library pubsubclient. This example will receive Node Red that receives data from the ESP8266 and allow control a LED connected to GPIO 02 from a…
That is MQTT ? In short MQTT is a TCP / IP protocol lightweight messaging, the model is publication – subscriber requires a message broker which is responsible for directing recipients through a topic in common. It is considered to Andrew James Stanford-Clark as the author of this protocol. More information MQTT Wikipedia. Official Website:…
