Control I2C Relay with Node-RED Dashboard in Smartphone. After working with an above different way to control I2C relay board with Arduino, let's control the I2C relay with Node-RED dashboard. For installation and to install the different nodes in node red in windows operating system please go through the previous blogtut. Node-RED is a visual tool for wiring the Internet of Things that can be run on a. Any hardware changes, just choose your desired I2C address with the A0, A1. MQTT Message consists of The ADS1115 is a device that converts Analog to.
This library provides a class for the ADS1115, it relies on the ncd-red-comm library for communication, and includes a node-red node for the ADS1115. The ADS1115 is a 4-channel, precision, low-power, 16-bit, I2C compatible, analog-to-digital converters. Ncd.io manufactures a few different mini-modules that utilize this chip for different applications, you can see a list here.
This library should work with the ADS1113 and ADS1114 chipsets as well, but it has not been tested.
Installation
This library can be installed with npm with the following command:
For use in node-red, use the same command, but inside of your node-red directory (usually
~./node-red
).Usage

The
test.js
file included in this library contains basic examples for use. The datasheet contains more information on specific settings. All of the available configurations are available in the node-red node through the UI.Raspberry Pi Notes
If you intend to use this on the Raspberry Pi, you must ensure that:
- I2C is enabled (there are plenty of tutorials on this that differ based on the Pi version.)
- Node, NPM, and Node-red should be updated to the LTS versions. If you skip this step the ncd-red-comm dependency may not load properly.
