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.
This library can be installed with npm with the following command:
npm install ncd-red-ads1115
For use in node-red, use the same command, but inside of your node-red directory (usually ~./node-red).
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.
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.
