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.

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…
