Node Red

Its been a while and I needed another MQTT “technology fix” to get my brain whirling so I revisited a challenge I looked at several years back — how to “shoulder tap” an MQTT device that had gone silent. For example I may have an application on a web page…

Here it is illustrated how to store sensor from Arduino serial port into MySQL database using Node Red. The sensor data is the humidity and temperature data from DHT11 module.This sensor data read and sent by Arduino to PC via serial port. On the PC, XAMPP is used to create…

Using wifi access points to pinpoint location for your smart home — Room presence detection (aka occupancy) is one of the most important aspects of the smart home. Why? Well, having a stable and predictable room presence detection allows you to know if a room is occupied or not and that leads to really advanced automations! Things like turning devices on/off when…

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a…
