Does anyone have experience using the Sharp IR distance sensor? I am trying to get distance data from one thru a raspberry pi to display on a data field on the Blynk app.

New to Node Red. Any help will be most appreciated. 🙂

Hello,  
Maybe someone else can give a better suggestion but I think, this way, described in the link, would be a good and flexible way. MQTT is a good choice, it is supported natively by Node-RED, it is used "everywhere" when connecting devices in computers and over networks. It also gives you freedom to easily share data to several consumers

Anyway, the concept is:

Sharp IR sensor -\> Cylon.js -\> MQTT ---------- MQTT -\> Node-RED
